Of those maybe two could do well at Villa, Jenssen and Berisha (I admit I don't know much about the last one), the other three are just not good enough. Drage has been poor so far this season, and Johansen isn't even in the team. The one thing we do know is that Solskjær wanted Kara Mbodj earlier, and he is truly to good for the Norwegian league!
I agree with Kara, but as I said, these players wouldn't cost the world and it wouldn't be anywhere near the sums we have spent on average British players before. Ole will also know first hand whether or not these players have the potential to make the grade.
