Arsenal are in talks to sign Valencia defender Cristhian Mosquera as the Premier League side ramp up their summer transfer business.

The Gunners want to make a defensive signing this summer with the 20-year-old Spaniard emerging as their favoured option.

Arsenal have shown an interest in Marc Guehi of Crystal Palace, but the England international maybe reluctant to join given he may find opportunities limited behind Gabriel Magalhaes and William Saliba.

Mosquera has made 90 appearances Valencia and was regular in the team last season. That included playing 90 minutes in 37 of the club’s 38 league games.

It has been a busy 24 hours for the Gunners, who are also on the verge of completing a swoop for Brentford midfielder Christian Norgaard.

A fee worth up to £15million has been agreed and the Denmark international is set to undergo a medical.

Meanwhile, Myles Lewis-Skelly has signed a new five year deal at the Emirates Stadium – following Magalhaes, who penned new terms earlier this month.

Cristiano Ronaldo's time at Saudi Arabian club Al-Nassr whom he joined in 2023 has been largely underwhelming.

Though he has bagged plenty of goals for the club and won personal accolades, the Portugal legend's only trophy at the Riyadh club came in the 2023 Arab Club Champions Cup, where he scored twice in the final to help his side beat rivals Al-Hilal.

Ronaldo will also have his fifth different manager at the club next season, after Al-Nassr parted company with Stefano Pioli after less than a year in charge this week.

The former AC Milan boss had taken over at the Saudi Pro League side in September 2024 when he replaced Luis Castro following a poor start to the season.

Pioli guided Al-Nassr to a third-place finish in the Saudi top flight last season as they finished 13 points behind champions Al-Ittihad.

They were also knocked out in the last-16 of the King's Cup and the semi-finals of the AFC Champions League.

Al Nassr have announced that Cristiano Ronaldo has extended his contract with the Saudi Arabian club.

The 40-year-old Portugal captain's deal was due to expire at the end of this month, having joined the Saudi Pro League club in 2023 after the termination of his deal with Manchester United.

He has scored 99 goals in 111 appearances for the Saudi club, including 35 in 41 matches last term, claiming the league's Golden Boot award for top scorer.

"Al-Nassr forever," Ronaldo says in a video posted by the club on social media with caption "the story continues."

Ronaldo posted on social media "the chapter is over" following the Riyadh club's final Saudi Pro League game of the season last month, leading to speculation he was set to leave.

Myles Lewis-Skelly may only be 18, but Mikel Arteta certainly trusts him.

Of all players aged 18 and under playing for Premier League clubs last season, no one featured in more games (39) than the Arsenal man.

A new contract and a place on the shortlist for PFA Young Player of the Season are reward for Myles Lewis-Skelly’s breakout season with Arsenal and England.

The 18-year-old was a ball-carrying central midfielder in Arsenal’s academy but has excelled at left-back, with license to step into midfield, since making his first Premier League start in December.

Lewis-Skelly’s running power and physical strength are among his key attributes. He was only dribbled past once in the Premier League, the best record of any player to have made at least 15 starts. He also ranked third for fouls won (3.1) per 90 minutes and won the most duels (6) per 90 among Arsenal’s defenders.

His background as a midfielder is evidenced by a 93.6% pass accuracy, the fifth highest figure in the division among all players to have featured for at least 1000 minutes during 2024-25.

As England head coach Thomas Tuchel said after giving Lewis-Skelly his first England call-up in March, “He’s nothing but impressive.”

Thank you to everyone who has texted in to tell us that the movie Burnley featured in their announcement video for Quilindschy Hartman is of course Stephen King's It.

My colleague and I might be the only people in the room to not know that.

Unless you are an Arsenal fan, there's a good chance you had no idea who Myles Lewis-Skelly was this time last year.

Manchester City striker Erling Haaland certainly had no idea when the then-17-year-old made his Arsenal first team debut in a fiery 2-2 Premier League draw in September. He even asked him: "Who are you?"

It's fair to say that everyone knows now.

A decade on from joining Arsenal's youth system, Lewis-Skelly made 39 appearances in all competitions in 2024-25.

In March the 18-year-old made his senior England debut, and has started three of Thomas Tuchel's four matches in charge of the Three Lions.

Whew. What a busy afternoon in the Premier League. Left-backs are certainly trending right now. Here's a summary of the latest updates:

• Liverpool completed their third major signing after left-back Milos Kerkez put pen to paper. The reds signed the Hungarian international for £40m on a five-year contract from Bournemouth.

• Myles Lewis-Skelly signs a new five-year deal at Arsenal. The 18-year-old fullback stated: "I'm definitely more ready now for the next season. I just want to keep learning and keep improving.I want a legacy. I want to win everything there is to win in the game."

• Newly promoted side Burnley sign their own left-back Quilindschy Hartman from Feyenoord. The 23-year-old is Burnley's second signing of season after purchasing 'keeper Max Weiss.

• Gossip: According to the London Evening Standard, Christian Norgaard could join Arsenal by this weekend after agreeing a deal with the Gunners.

Stick around for more updates, done deals and all the latest gossips coming your way throughout the day.

Yesterday Burnley published a clip from 1996 classic Mission: Impossible, in which Ethan Hunt (Tom Cruise) has his head placed in a sack and is taken to see somebody called Max.

The sack is removed and sitting in front of Cruise is..... Burnley's new goalkeeper Max Weiss, external. Obviously.

If you are in the least bit social media savvy, then you might know that Burnley have a reputation for confirming new signings with quirky announcement videos.

The arrival of Quilindschy Hartman is no different.

They've cut the Dutchman into a film, external (we're not sure which one, please help us) in which a child is chasing a paper boat along a gully of rainwater.

When the boat dissapears down a drain, the child peers in and finds.... Quilindschy Hartman, of course.

It's all rather odd but brilliant at the same time. Honest.

Burnley have completed the signing of left-back Quilindschy Hartman from Feyenoord for an undisclosed fee.

The 23-year-old Netherlands international has agreed a four-year contract.

Hartman becomes Burnley's second signing of the summer following the arrival of goalkeeper Max Weiss from Karlsruher yesterday.

Stop what you're doing immediately - there has been another left-back signing!!!

After signing his new five-year contract with Arsenal, Myles Lewis-Skelly told the club's website: "I’m so proud and happy. I know those words are simple, but I think they sum up how I feel signing for this club. I’m a fan and it’s like a dream come true.

"I've embodied the values of Hale End and come through. I've still got a lot of years ahead of me, so if I can keep staying humble and being a good person, that's the most important thing to me."I know I've taken a lot of experience from the games about the positive moments, the mistakes that I've made. I'm definitely more ready now for the next season. I just want to keep learning and keep improving."I want a legacy. I want to win everything there is to win in the game. I want to win trophies on the biggest stages whilst being a person that's always learning and stays grounded, which is so important."

Milos Kerkez spend his early days in football at clubs in Serbia, Austria and Hungary including Rapid Vienna, Vrbas and Hodmezovasarhelyi.

Early in 2021, Milos Kerkez was convinced by five-time Champions League winner Paolo Maldini to choose AC Milan he left Hungarian side Gyor.

He was given some minutes in pre-season in summer 2021 but always ranked behind Milan's more senior left-backs Theo Hernandez and Fode Ballo-Toure.

Kerkez departed for AZ Alkmaar in January 2022 having never played a competitive match for the Serie A club.

The Hungarian told journalist Gianluca di Marzio that asking Milan to leave on a permanent basis was "the best decision of my career".

The following season Kerkez played in all but one Eredivisie match as AZ finished third, and he helped his side reach the Europa Conference League semi-finals where they lost 3-1 on aggregate to West Ham.

From there he moved to Bournemouth for an undisclosed fee in summer 2023, where he quickly became one of the standout stars.
