I doubt I have a more extensive knowledge of football and footballers than roberto Martinez, but I can still tell you that Alcaraz, McGeady, atsu and niasse were poor players and bad signings.
Just saying 'the manager knows what he's doing' is fine, but fans wil always have their opinions - that's why there's a forum.
I've seen a fair bit of bolasie and I don't believe that he's worth the sort of fee being quoted. I'm also slightly concerned that we're strengthening an area we're already pretty solid in before bringing in players in positions which appear to be a weakness.
If we're able to strengthen other areas too then I'll feel a lot better about the whole thing, and either way any player pulling on the blue shirt will have my 100% support when it comes to it.
