Manchester United reportedly chasing Argentina star

Manchester United are reportedly interested in signing Benfica midfielder Enzo Pérez, who is currently starring for Argentina at the World Cup. The latest report comes from John Cross in the Mirror, though his claim that United are looking to hijack Valencia's £20 million bid isn't a new one. That was first reported by Portuguese site O Jogo back in May.

It's perfectly plausible that there's just some rehashing going on here, and no new intelligence has come to light since O Jogo's initial article. But after Pérez's impressive showing in front of Louis van Gaal the World Cup semifinal last night, the reports are at least a little intriguing.

Pérez would seemingly be a very good signing for United -- he's energetic, an excellent passer and a tough tackler. Just about everything you'd want alongside Ander Herrera. He even won Benfica's player of the season award earlier this year.

However, he's 28, and while he'd be a good signing, he wouldn't be a great one. If he was going at £10m, United shouldn't hesitate. At £20m, Pérez wouldn't exactly be a sound long-term investment, and the Red Devils would probably be better off forking out for a younger, better player. TBB would be surprised if there was any truth in this rumour.
