This season has provided a few questions for Manchester United, not least in midfield where £27.5 million man Marouane Fellaini has failed so far to provide answers.
Fans probably feel the club overspent for the former Everton man, so how about the club offset that negative view by pulling off the deal of the summer in 2014?
Step forward Blaise Matuidi, PSG's midfield dynamo who is an automatic starter for the French champions.
Matuidi is yet to agree a new contract, and his current deal expires next summer, meaning clubs are able to talk to him and sign him to a pre-contract agreement from January 1.
Just last month he was non-committal over his future, telling L'Equipe: "I am really at ease at PSG, my first wish would be to stay. But you can wish for something and sometimes it doesn't happen. The club has a special place in my heart, but anything can happen in a career."
Valued at €18 million, Matuidi is a central midfield player who has it all.
He ranks in the top five players in Ligue 1 for pass completion (91.5 per cent), and is the second most prolific tackler in the PSG squad, his average of 2.6 per game would rank above any United midfielder this season.
Matuidi is also the most prolific PSG midfielder in terms of interceptions, with an average of 1.6 per game, while he also has two goals and two assists to his name this season.
He is a current French international of 15 caps, and was integral to PSG's title success last season, playing 37 times.
If they were able to sign the midfielder on a free transfer, it would be a fantastic deal, although they should beware that Chelsea are also hovering.
There is one possible negative however, and that is his agent, Mino Raiola. He is also Paul Pogba's representative, the same one who helped engineer his switch away from Old Trafford.
