Fair enough. Can't say I've got giant knowledge about Everton so I'll leave that to your judgment. Mucha's a bit younger so he has time to prove his worth.
Some additional info if anybody cares: He sat on the bench for a year when Fabiański was goalie in Legia until he moved to Arsenal in '07. He was no-ones favorite, but proved his worth. Kept a clean sheet for 634 minutes in 07-08 and appeared in all the games last season. Him about moving to Everton: "I am an ambitious guy and I always said that I love English football and English weather. Despite my affection for Premiership I rejected the first offer made by Everton. After proving my worth with Arka (our defense last season was basically non-existent and it was up to him to save our skin) they came back with an offer I just couldn't refuse. I'm interested in playing proper football, offers from Spain, Italy and France are all good, but secondary when it comes to fulfilling my dream by playing in England." He was picked footballer of the year with 70% of votes. Other English clubs that were interested in him: Wigan, Sunderland, Tottenham, Arsenal and Stoke. I saw Arsenal's scouts myself on a number of occasions. I'm glad he's moving to Everton though, I hope you guys will greet him warmly on Goodison Park.
He really should pay me for this good pr, but he doesn't
