Ten years ago, 4-4-2 was the way to play football. It was the formation all the best teams in the league were using. At that time, we were experimenting with 5-3-2 and Christmas tree formations.
Over the last few seasons it has changed. Liverpool, Chelsea and Manure are all using the 4-5-1 formation now and it's separating them from the rest of the league by a large margin.
4-5-1 worked well for us last season. It worked very well today. With our current abundance of central midfielders, we could employ this system and switch players regularly, so they don't all become knackered by the middle of February.
4-5-1 every time.
