That is not very impressive for a central midfielder in my opinion and here's why. His tendencies to go heroic aren't just limited to taking unwarranted shots but also his love for hollywood balls quite a few times some of which are straight to the opposition. Again, that works in an average team who have put him responsible of scoring as well as creating, but I don't regard him as a very creative player who is a genius with his passing and vision. In this game, again, that would be a problem when someone playing in that position should be playing a more disciplined role letting others do the majority of the creative and attacking work. Does he have it in him to give up those tendencies and let others get their names on the final pass/goal? Or will his hero-ball be a distraction and cost the team possession while not letting the better players on the ball get more time on it?
No doubt about his off the ball game and the all action qualities he brings to the table but I would say the need of the hour here is a more disciplined, technically astute team player who has better decision making and usually lets the playmaker get on with it while concentrating more on his defending, covering the midfield and supporting the primary offensive unit. In that Milan diamond you won't have Seedorf or Gattuso concentrating playing their own game and taking shots or attempting hollywood balls as per their will, but rather give it to Pirlo or Kaka as soon as possible. The one quality Gerrard would be great with is driving with the ball, but if he tries too much to get that final action himself be it a goal or an assist attempt then it would distract from what the team is trying to achieve. Basically he needs to be a low usage player here, while he has been a very usage player for all his career.
