A fully fit Vaughan is a huge boost for Everton, he is different from our other strikers, he has electric pace, not afraid to throw his weight around (why he has had so many injuries) and is willing to bide his time to get a chance in the first team.
I would take Vaughan over Anichebe anyday, he does have the potential to be a great striker if he can just keep himself fit, he doesnt know when to give up and runs defenders ragged, if Agbonlahor can play for England then Vaughan definately can
All he needs to do is be a little less enthusiastic on the pitch, he runs into a challenge at 90 miles an hour when he doesnt need to, but can he really be blamed for going into a challenge the way he does.
The brazillian Ronaldo has had Cruciate Ligament Damage in both knees but has scored 5 in 10 games this season for Corinthians, there is an example of how you can come back from serious injuries (even though Ronaldo is in a league of his own in marks of quality)
