Transfer news: Manchester United step up chase for Internazionale midfielder Fredy Guarin - reports

Manager Moyes has sent out representatives to watch the Colombian

Manchester United manager David Moyes has reportedly sent out representatives to watch Internazionale's Fredy Guarin ahead of making a January offer for the midfielder.

The 27-year-old has been identified as the player needed to bolster Moyes' struggling midfield, in which he has largely played 40-year-old Ryan Giggs and centre-back Phil Jones in the middle of this season.

Guarin is well known to one current Premier League manager - Tottenham Hotspur's Andre Villas-Boas, having won the treble under him at Porto in 2011.

The Colombian can also play in the Champions League knockout stages, as Inter finished ninth in Serie A last season. Guarin joined Inter from Porto for £9m in May 2012, turning his loan deal permanent.

It was been reported that Inter could be open to an offer of £15m for the midfielder.
