It is wiser to start him on the pitch, because sometimes he gets tired sooner, sometimes later, so just sub him when he is tired, same goes for the rest, DP is still a starter, everybody has on and off form period, this is were the rotation helps to rest some players and take the maximum from everybodyI dont think DP reacts well when he has the sub status, but he can handle it, the team cant though, he is our captain and as long as he is there, he has a double role, our team lacks cohesion and morality without him.
When we use a 3 man attack DP has to be on of those 3 and Treze too!
