Manchester United are reportedly ready to rival Chelsea for the signature of Joao Moutinho.
The FC Porto star has emerged on the Stamford Bridge radar following the arrival of Andre Villas-Boas in west London, with the former manager looking to raid his old club for a number of players if reports are to be believed.
However, Manchester United have joined the race for the player, according to Portuguese publication Diario de Noticias, which claims that Sir Alex Ferguson has been tracking the player.
Ferguson has been in contact with old Manchester United number two Carlos Queiroz in the past, according to the report, with the pair discussing the player during his time at Sporting Lisbon.
Villas-Boas is credited with reviving the players career when bringing him to the Estádio do Dragão back in the summer of 2010, and could look to get the best out of the player again if he decides to bring him to Chelsea.
Radamel Falcao and Hulk have also been tipped to make Chelsea moves in recent weeks, although the 33-year-old manager was coy on transfer talk when introduced to the media earlier today.
"I'm more than happy with the squad. It's nothing new that when a manager comes changes are expected. But bearing in mind the success the club has had in the last six or seven years, we have to adjust things carefully and make wise decisions," said the Chelsea boss.
"We have top quality players and I want them back as soon as possible. I'm counting on everyone coming in from last year and then we will make decisions. We have plenty of time in the market."
Manchester United are known to be in the market for a playmaker, with the Old Trafford chief searching for a replacement for Paul Scholes this summer.
Wesley Sneijder and Luka Modric have also been linked with the Red Devils, and now Moutinho is a potential fourth addition following the arrivals of Phil Jones, Ashley Young and David de Gea already at Manchester United this summer.
A bidding war could be triggered between both clubs, but the past relationship between Villas-Boas and the player is likely to make Chelsea favourites as the manager looks to strengthen an ageing midfield containing Frank Lampard and Michael Essien.
