He said: "He was the beating heart of that side and I think he's a terrific midfielder." He's strong, he's got quality, he's got a good engine – he's one of the best all-round midfielders, potentially, that I've seen come out of South America in a while.
"Get him, sign him on!
"Ecuadorians are only just starting to forge careers in Europe." Antonio Valencia has done a lot to open doors for them, he's just left United and gone back to Ecuador.
"But this fellow Cifuentes strikes the ball well, moves across the field, strong in the tackle, strong on the ball, I like him a lot."
