While i agree 4-5-1 is a good formation and away from home can we effective against stronger teams, all this talk about our defence being so much stronger in this formation while goals being scored is not effected is rubbish.
Last season we had a bloke call Martin Laursen, do u remember him? he was a great leader, an awesome defender, was our target man in set pieces and most of our great results in the 4-5-1 had him playing. Also Ashley Young and Gabby were in great form.
