My perfect formation would be 4-3-3 with one holding and then the two going forward. I would be one of the ones going forward.
I've always preferred a 4-3-3. It's a more fluid and dynamic system, and I think it plays to my strengths better.
If you are playing on the left of a four-man midfield, there are a lot more defensive duties to do, so you can't find the times to keep attacking. But if you're on the left of a 4-3-3, I find that position really good as well.
I came from Ajax where you play 4-3-3 and as a winger they didn't want you to defend.
I don't really like all these tactical systems people talk about: 3-5-2, 4-3-3, and all that.
If you're talking about English football very few teams play 4-4-2 now: it's either 4-4-1-1, 4-3-3 or 4-2-3-1, they are the three major systems played throughout the Premier League.
I was only used to 4-3-3. For me as a left-winger you have also a left midfielder and a left-back behind you. But in a 4-4-2 you are basically also the left midfielder so you have to help more in defence and I wasn't used to that.
I prefer playing in a 4-3-3.
