Arsène Wenger believes that the expectation for clubs like Arsenal to sign big-name players can make their transfer activity more difficult.

Arsenal face Swansea City in the FA Cup on Sunday, with Michael Laudrup’s side containing a number of top-quality stars who were not widely known in England before this summer.

Wenger says it is not an easy trick to pull off, especially with the demand for the addition of the highest-profile players.

“It's very difficult because the level of expectation is very high,” the manager said. “People want to see Lionel Messi. They don't want to see a promising guy.

“First of all the name gives hope. When a guy has no name people are already sceptical. So it's much more difficult for us.”

One of Swansea’s biggest hits this season has been Michu, who has 14 goals in all competitions after joining from Rayo Vallecano in July. Wenger admits that the Spaniard was not on his radar, although he had heard of him.

“He was a guy who disappeared a little bit,” he said. “He was at clubs where he was bombed out and so you always think, ‘OK, he doesn't make it there so why should he make it here?’ But he has done extremely well. It looks as if it is not accidental what he is doing, he is a really good player.”
