One question - would Wellbeck have contributed more than Rooney did?
Answer: It would have been difficult for him to contribute less.
I have never been convinced when it comes to Rooney - he still lives on his achievements aged 16 and 17 to me. He did nothing at WC 2010 and nothing here. Yet we bring him when he can't even play in the first two games, which we did fairly ok in, and change the team, the shape, the spirit to try and crowbar him in. Why? Other nations don't do this - if you are out suspended you have to break back into the team. We had the same with the Gerrard/Lampard situation, "they are both good so they must both play" mentality - it's total rubbish!
Another thing your Germanys, Italys and Spains don't do is persevere with mediocrity. Sorry, but a Spanish version of Milner or Ashley Young would have struggled to make the bench after their contributions (or lack of) but we stick with them time and time again, and watch people like Milner put crosses in 3 yards behind the strikers (or 10 yards into the crowd behind the goal. We have to accept some are good at their clubs but can't cut it at international level and leave them and move on. How many years of this did we get with Heskey?
Teams win the major international tournaments - not so-called World class players. A team won last night, did you notice that?
