William Carvalho remains a possible candidate for a Manchester United transfer this summer, although the Red Devils are yet to pull their trigger on the deal.
The Sporting Lisbon midfielder has said he is happy enough to remain in Portugal, but don't expect him to resist if a big club comes calling.
United are not Carvalho's only possibility however. The switch of Sporting manager Leandro Jardim to AS Monaco makes him a natural candidate to sign with the big-spending Ligue 1 side.
Monaco signed midfield Geoffrey Kondogbia last summer, a similar type of player but one who has failed to have instant success, making just 16 starts. If Jardim sees Carvalho as an upgrade, don't be surprised to see him make a move.
PSG's own plans however make them candidates to enter the race too. Already possessing a star-studded midfield, the French champions appear keen to add one more powerful midfielder, linked with Yaya Toure and Paul Pogba.
Both appear likely to be out of even their reach, and Carvalho is a more affordable, and attainable solution with Sporting willing sellers at the right price.
Being able to one-up their rivals, who will be desperate to usurp PSG's status as champions next season, will be a key blow and keep a promising player out of Monaco's reach.
With all of this bubbling under the surface, Manchester United need to decide whether Carvalho is a player they really want and pay the price, because if they dally too long, just like Kevin Strootman last summer; they risk missing out.
