Klopp would still be a great choice for me, he's struggling a bit this season but he has still built great squads with small budgets. I also like how they play.
Rudi Garcia at Roma seems to be doing great work, I have been really impressed with the Job he has done there, he has built a really decent team, lots of good young talents like Iturbe mixed in with veterans like Totti and Maicon.
He also has players like Gervinho playing at a really high level. I watched Roma the other week against Man City and they more than matched them, was very impressed, I really liked the football they played too, really high tempo passing game.
