His performances in Russian Federation - and for Leicester in the Premier League after signing from Hull City in a £17m deal last summer - mean he has attracted interest from Jose Mourinho, who is believed to have made Maguire his top target ahead of the new season.
The former Manchester City defender is by no means United's first choice but such is Mourinho's dissatisfaction that they need contingencies.
Manchester United were linked with a swoop to sign Belgium defender Toby Alderweireld from Tottenham Hotspur. They could not have done better than what they did. United should ideally persist with Martial and try to transform into a more focused individual than spend on someone who can, at best, give them 2 good seasons.
United were beaten 1-0 by Bayern Munich at the Allianz Arena, five days before their Premier League campaign begins at home to Leicester.

Mourinho has been forced to operate with a thread-bare squad for much of pre-season and that predicament has not been helped by the arrival of just three new signings.
Instead, with a full pre-season behind him, the hope is that Sanchez displays a new lease of life having struggled to adapt in the final months of last season. If they can't, or won't, United will look slow and stagnant when they attack.
At full-time, the Portuguese compared his youthful team to the raft of talent at Bayern's disposal, including experienced players such as Robert Lewandowski and Arjen Robben.
