Arsene Wenger has admitted that it will be "very difficult" for him to pick his best team for Arsenal's FA Cup semi-final against Reading, with the majority of his players fit for the fixture.

Jack Wilshere is ready to return from injury this weekend, leaving Mikel Arteta and Alex Oxlade-Chamberlain as the only players unable to feature against the Royals.

The manager said at his pre-match press conference: "We have a massive squad of 24 players at the moment and there are also players on loan. It's important to get the right dimension.

"We know each other better now and have a better balance in our team between attacking and defending. All the players have top, top quality, which makes it very difficult for me to pick my best team.

"They all deserve to play. [Wojciech Szczesny] will play on Saturday. He had a very good performance at Manchester United."

Arsenal are attempting to lift the trophy for the second year in a row, having beaten Hull City in last year's final.
