He'll be 35 2 months into next season, the stats you're posting look good due to the league he plays in. CL record is good though no arguments there. He will not come to sit on your bench and will want silly wages, when not getting his own way he is sulky and lazy. He's looking for a big money move to line his pockets before retiring and will drag Utd further into the mire...yeah you should sign him.
The Champions League stats are decent, I'd hardly say they are outstanding though, they are also over such a small period of games, so it's hard to make any significant conclusions from them. They are probably helped too by the fact he's supremely confident as he scores every week against the rubbish in France. How well would he be doing in the CL, if his confidence wasn't being boosted week in week out in France.
Jose is also a huge fan of Didier Drogba, but don't think we'll be getting him out of retirement for next season.
I think what's going on at the moment almost certainly involves Mourinho sobbing to his agent (again), asking "Why don't Utd want meeeeeeeeeeee?"
