London Irish winger Alex Lewington has caught the attention of England head coach Stuart Lancaster, according to Exiles interim boss Glenn Delaney.

The 23-year-old has scored two hat-tricks this season and is joint-second in the list of Premiership try scorers, with eight scores for the Exiles.

"He's certainly grabbing the attention of Stuart Lancaster, which is right - he's on great form," Delaney told BBC Radio Berkshire. "Alex has got a huge amount of talent. He's improving and learning a lot."

And Phil Parkinson adds the money generated for Bradford's club coffers by the Reading match is not a priority for him.

"It's more than being about finances at this stage, it's about the prestige and the chance of getting to the semi-final of the FA Cup," adds the Bantams boss.

Bradford City must seize the advantage of being handed a home tie in the FA Cup quarter-finals, insists manager Phil Parkinson.

"We wanted the home draw and we've got that, we can't argue with the opportunity presented to us at the weekend," he says.

Promotion-chasing League One side Bradford have already beaten Premier League leaders Chelsea and Sunderland on the way to the last eight.

So Championship strugglers Reading should be a piece of cake, right? Of course not, says Bantams boss Phil Parkinson.

"Reading have a lot of players with Premier League and international experience, we're just looking forward to testing ourselves," he says.

"We don't fear Reading but we definitely respect them. There is an air of confidence amongst the team and as individuals.'"

The Valley Parade pitch should not be a problem for either Bradford or Reading in Saturday's quarter-final tie, says Bantams boss Phil Parkinson.

Sunderland boss Gus Poyet labelled the pitch as "one of the worst in the country", external after his side's defeat there in the last 16.

"Reading's pitch isn't in great condition either, they'll be used to playing on a heavy pitch. But the weather up here in Yorkshire is good," says Parkinson.

Saturday's quarter-final tie promises to be a special occasion for Bradford City - and particularly their manager.

Bantams boss Phil Parkinson is a Reading legend, having played over 400 times for the Royals and being named as one of the finest central midfielders in the club's history.

"For me personally, it will be a special day. It's a game of real importance and I'm really looking forward to it," he says.

"'I was very honoured to be part of the club that moved from Elm Park to the Madejski Stadium and part of the development."

Talking of the famous old competition, it is time to find out what another quarter-final manager has got to say for himself. Next up in front of the media is Bradford City gaffer Phil Parkinson...

"It's an astounding figure and something that will definitely help sustain the club for seasons to come."

The words of Warrington Town chairman Toby Macormac when his Northern Premier Division One club reached the FA Cup second round earlier this season.

But exactly how much do Warrington, and other clubs right across the English football pyramid, earn from FA Cup runs?

If there is one match that a Barcelona player does not want to miss it is El Clasico.

But that fate might fall on Barca midfielder Sergio Busquets. The Spain international is battling to be fit for the home La Liga match against Real Madrid later this month.

What is for certain is that Busquets will miss Sunday's top-flight clash with Rayo Vallecano after limping out of last night's Cop del Rey win at Villarreal.

India batsman Virat Kohli has been a naughty boy.

He's been warned about his future conduct by the Board of Control for Cricket in India (BCCI) after getting into an altercation with a journalist during nets practice for India's next match against West Indies.

Apparently it was a case of mistaken identity, with Kohli wrongly believing the journo in question was the author of an article which had upset him.

"The draw has been made and the tie will begin at 13:00 GMT on Friday with Andy Murray v Donald Young, followed by John Isner v James Ward.

"The doubles nominations see Jamie Murray and Dom Inglot in line to face the Bryan brothers, although that can change up to an hour before the match and there is every chance that Andy Murray could yet feature on Saturday.

"It will all be live on BBC TV, radio and online."

Brighton & Hove Albion winger Kazenga LuaLua says he will not stop his back-flip goal celebration despite the club's concerns after a knee injury that kept him out for 10 weeks.

The 24-year-old scored for the first time in more than three months in Tuesday's win over Derby County.

"I know the staff don't like it when I do a back flip. But I don't think anyone can stop me - it is how I celebrate," he told BBC Radio Sussex.

England's summer friendly against the Republic of Ireland in Dublin will kick-off at 13:00 GMT on Sunday 7 June, announce the Football Association of Ireland.

The two nations will meet at the Aviva Stadium ahead of the European Championship qualifiers later that month.
