Arsenal's new Brazilian defender Gabriel Paulista has all the qualities needed to be a big hit in the Premier League, according to manager Arsene Wenger.

The Gunners have signed the 24-year-old from Villarreal in a £15 million deal, with Costa Rica striker Joel Campbell moving in the other direction on loan for the rest of the season.

Wenger said: "He has good pace, is good in the challenge and is tall, so he can adapt to English football.

"Maybe it will take some time to adapt completely, but overall it is very good to have him."

Super League champions St Helens say their World Club Challenge game against NRL champions South Sydney Rabbitohs on 22 February at Langtree Park is a sell-out.

The match is the climax to the expanded series in which Warrington and Wigan host St George Illawarra Dragons and Brisbane Broncos respectively.

Saints chairman Eamonn McManus said: "It's no exaggeration to say that this World Club Final represents the biggest day in the proud history of both the club and the town of St Helens. Although we have won it twice, this the first time we've participated in it on our own turf."

India batsman Yuvraj Singh has been named as the final member of the MCC's squad for the Emirates T20 tournament in Dubai in March.

The 33-year-old joins England Test captain Alastair Cook in the squad, which was announced last week.

The MCC will take part in the T20 tournament with Lancashire, Sussex and Yorkshire in Abu Dhabi on 20 March.

Yuvraj will not play in the four-day day-night game against county champions Yorkshire, starting on 22 March.

Dorus de Vries is in talks over a new contract with Nottingham Forest, the Dutch goalkeeper has told BBC Radio Nottingham.

The Sun, external: West Ham have put in an £8m bid for 29-year-old Swansea striker Bafetimbi Gomis. However, at his news conference today, boss Sam Allardyce appeared to rule out a move for Gomis, saying "we have more than enough frontmen to cope".

Press Association Sport reports that Chelsea striker Diego Costa is contesting the Football Association charge of violent conduct.

The Spanish defender was in the last six months of his deal at the DW Stadium but has been allowed to join Levante.

Ramis made 20 appearances for Wigan this season.

Chelsea have cancelled tomorrow's Jose Mourinho news conference.

No reason has been given. Could Jose be upset at the £25,000 FA fine he got hit by, or the FA charge for Diego Costa's alleged stamp?

We'll no doubt find out at some point over the next few days.

Chelsea face Manchester City on Saturday (kick-off 17:30 GMT).

After Mali and Guinea had to draw lots to see who went through at the Africa Cup of Nations, we asked you for alternative ways to settle it. Your thoughts so far...

Chris Dales: The coaching staff should have a sudden-death penalty shoot-out to decide who goes through

Richard Todd: Mali and Guinea settle who goes through by taking penalties, but run from the halfway line like in ice hockey

Paul Dove: It should be decided on who had the most corner kicks during the three games so the most attacking team is rewarded.

MJ: Fair or unfair, it's written into the rules. Every team knows the score beforehand but only when it happens do they complain.

And our favourite so far...

Alex Tomlin: Keepy-uppy tennis ball challenge to decide who goes through in Africa Cup of Nations. Fairer and more entertaining.

Genoa fans are being urged to boycott the opening stages of Saturday's Serie A match at home to Fiorentina in protest at recent refereeing decisions against them.

"We invite you to desert the stands of the stadium in the first 10 minutes. We are no longer willing to put up with these refereeing injustices," said a statement signed by the club's organised supporters groups.

Genoa were livid after losing 2-1 at Napoli on Monday, saying that neither of Gonzalo Higuain's two goals should have stood, believing he was offside in the lead-up to the first goal and claiming that the penalty he converted for the winner should not have been given.

Scott Mitchell says he will enjoy the added pressure brought on by his new status as BDO world champion following his triumph at Lakeside.

The 44-year-old will compete at the Dutch Open in Assen on Friday.

"There is pressure. I've had a target on my back for a couple of years but it's just that it's bigger than it used to be," he told BBC Radio Solent.

"I think I'll enjoy it. It's a great honour to be world champion. The attention is different but I'm the type of guy that won't let it get to me."

Manchester United midfielder Nick Powell, 20, could be handed a chance to revive his career by Hull's Steve Bruce, reports The Mirror, external.

The Tigers are aiming to sign the player - who is back at Old Trafford after an unsuccessful loan spell at Leicester - until the end of the season.

And lastly from Brendan Rodgers, he was asked about his rivalry with Jose Mourinho.

"There is no needle," said the Liverpool manager. "I think that I said how good my team was afterwards and I obviously made some points I felt were relevant but that is gone.

"The most important thing for me over the course of the games was the team is returning to the top level of performance.

"I thought we were outstanding in the games and of course you are disappointed when you don't make the final but we have gained a lot from that competition in the last four months of the season and I hope we can continue to develop."

A last few bits to tie up from Brendan Rodgers' chat with the media.

The Liverpool boss said Raheem Sterling sees his future at Anfield and hopes his contract situation will be sorted soon. Real Madrid is the latest club to reportedly show interest in the England international.

"It's all in hand with his representatives and the football club. Raheem is very happy here," said Rodgers.

"He's a young player who is playing at one of the greatest clubs in the world. He sees his long-term future here. He's very happy with his progress, he's a real sponge for learning. He knows he's in the right place to develop and be looked after. I am sure it will be sorted very soon."

Rory McIlroy is another shot back along with defending champion Stephen Gallacher.

Bradford City striker Aaron Mclean has returned to Peterborough United on loan until the end of the season.

The 31-year-old had spent the last three months on loan at Posh, scoring once in 10 games.

He left London Road to join Hull five years ago and moved to Bradford in January last year.

After Mali and Guinea had to draw lots to see who went through at the Africa Cup of Nations, we asked how you for alternative ways to settle it. Your thoughts so far...

Jake Adler: Each player should take on their opposite number in a game of Rock Paper Scissors. 11 v 11 Someone has to win.

Kenneth Barr: Play a thirty minute mini match (15 mins each way) a la extra time. Still no result? Then the dreaded penalties.

Tom Mill: Fight to the death. First side not able to field a team for the quarter-finals, by default, bows out. It's the only fair way.
