Casemiro has to cover the gaps left by everyone. That's balance for me; to make sure the game doesn't go mad.
For me, it's easier to play with my right foot. It's simple. If I go right, I see Diego and have different solutions: I go alone or pass to Diego, or the midfield can join in. If I go the other way, the cross with my left foot is not good.
If I don't get the service or if I don't the ball in the box, where I want it, I start drifting into midfield. I go and look for the ball. I try to be important for the team in other areas.
Tevez is an extraordinary striker. Not only does he score goals, but he also helps his teammates and the midfield, too.
I would love to play alongside Wayne Rooney. He does the running of two or three players and makes a lot of space. We would be the perfect combination.
I often felt as a player in a 4-4-2, you end up being outnumbered in midfield and chasing the ball, so as a manager I liked wingbacks to push forward; it gives the midfield player on the ball three or four options.
With a line of six in the defence and then three in front of that, it's not always easy to find the spaces to score the goals.
Mario Mandzukic works so hard for his team. He's not only a No. 9 but also runs behind the defenders and drops into midfield.
As a full back, your role is just as much in playing in midfield, getting forward and creating chances, as it is stopping them at the other end.
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.
All coaches now look for forwards who not only score goals but also run back and help in midfield.
When you've got players like Carlos Sanchez, Fabian Delph, and Tom Cleverley behind you, it makes it easy with Christian Benteke and Gabby Agbonlahor in front of me.
As England manager I always felt we needed an extra man in midfield to retain the ball, but that was more as an attacking ploy to help create opportunities. It came from my experience playing international football in a 4-4-2 and spending half my time chasing the ball.
