I don't understand why you guys ae so obsessed with terms like midfielder, wingers, strikers...etc. Ronaldo is a winger yet he scored more goals than all ManU's strikers combined! In modern day football, all players have to switch positions, improvise and connect with teammates.
Our downfall in the Stoke game was the players did not combine well. There was no understanding between Torres and Keane, a sad fact. The rest of the players like Gerrard and Kuyt tried to set up Keane but failed because Keane lacked movements! When the communications between players broke down, they got frustrated and attempted to shot themselves outside the box. That was the problem!
To solve it, we must restore back to the Torres/Gerrard axial. The two have much better understanding. The players are too keen to help Keane to get his first goal, they are forgetting their normal play!
