why 4-5-1 wont work!

the reason i believe system wont work for us is? we dont have type personell {pace} but main reason is teams use our 4-5-1 to there advantage! they have only one forward to look after so frees up player to go man for man on pw so taking him out of game, also frees another player to help double up on cb taking him out aswell! you only need 2 defenders for 1 forward!!! result is we are blocked from going forward unless we hoof it up but then got no one supporting helgasun same thing last season pw often taken out game for same reason! to me 442 is best option as other teams cannot man mark both pw or cb without weakening themselves, especially if we keeep winger out wide at all times it will stop doubling up on cb !! just an observation! be interesting to see what happens next week when we will have our best eleven available! finally there must be way for malky to utilise the 2 best players (cb&pw) outside premier more effectively!!!
