Last season's Premier League runners-up have stuttered in the market this summer, having so far only signed Brazil midfielder Fred, promising full-back Diogo Dalot and third-choice goalkeeper Lee Grant.
Manchester United appear to have missed out on Jerome Boateng after he agreed on personal terms with PSG, according to reports in France. The French defender is said to have taken advantage of a 2019 exit clause at his current club VfB Stuttgart.

The 2017-18 German champions are rumored to be demanding a 50 million euro transfer fee.
While this does seem like a sensible call on the part of the 29-year-old, it also frustrates United fans who wanted a big name to enter the fray and facilitate a charge for trophies.
As reported by Le Parisien, Boateng, who is contracted to the Bundesliga champions until 2021, has allegedly been allowed to leave the Bavarians after the club grew exhausted of his disciplinary issues over the years.
It now looks likely he will stay at Bayern - Boateng has a good relationship with new coach Niko Kovac who hails from the same district in Berlin.More news: Tiger Woods targets place on the USA Ryder Cup team
"So what went on there I really don't know".
Boateng is now tipped for a return to Manchester, but with rivals United.
"Well you do wonder what's going on behind the scenes because this is mysterious and curious that Manchester United have been so quiet", Darke said.
United have been heavily linked with Leicester star Harry Maguire, as well as Alderweireld, but have been put off by their respective asking prices.More news: Gal Gadot races into the cast of ‘Ralph Breaks the Internet’
