Its not weak at all, its ambitious which is admirable from a small/medium sized club. Its a similar thing to leicester last season. It would be weak and stupidity if they didnt live up to their goal but they made it convincingly to a semi final which is a big feat and they are by not approaching this game with an underdog mentality either, which of course you might expect from europa league teams in a similar position this season.
This aint the first time they played their B team when it doesnt matter. Back in december they played their second team against leverkussen having already qualified. In addition, this team has come from the qualifiers, beating fenerbahce and villareal on the way. They deserve respect theyve earned it but its time we knock them out.
