As the French fullback appears increasingly likely to leave Old Trafford this summer, joining former Fergie favourites Nemanja Vidic and allegedly Darren Fletcher out of the club, United have the hugely unenviable task of replacing not just one former stalwart of the team's successful period, but three.
And while United possess options in both central defence and central midfield, however underwhelming they might be, at left-back they have very little at the club to come in and replace French international Evra, a three time PFA Team of the Year player. Currently only Alexander Buttner is capable of taking Evra's place, though with just 665 minutes spread across 10 appearances this season, he might be on his way out too.
Considering that this spot in the team may be the most pressing to address, below we list five of those rumoured to be on United's radar:
How United must wish they had moved for Shaw last summer. The Southampton full back has gone from strength to strength this season, playing his part in the Saints' impressive campaign and winning his first England cap. Now in with a real shot of keeping Ashley Cole out of Roy Hodgson's World Cup squad, Mauricio Pochettino says he is already one of the best in the world in his position, and with Chelsea, Man City and Real Madrid also interested, any transfer fee may be around the £30 million mark if United can indeed bring the youngster to Old Trafford.
In contrast to Shaw, Coentrao has suffered the disappointing season that caused him to push for a move out of Madrid last August. Playing just 10 games despite Real's busy campaign, Coentrao may yet be the club's best bet of a top class ready made replacement for Evra. And because of his frustrating season, he should cost significantly less than the likes of Shaw or Baines.
Like Shaw, this ship may have sailed, especially considering Everton's surge ahead of United in the table and the expansive passing game Martinez has implemented there. But never underestimate the pull of Moyes on someone he managed so long at the Toffees, while a £20 million bid for a 29-year-old plus the sort of wages United could offer may convince club and player to reconsider a move.
The young Sevilla left-back has only been playing in the first team for two seasons, but has already broken onto the fringes of Spain's World Cup squad. Moreno was first choice as the Spanish Under-21 team won the European Championship in 2013, and since then has seen his stock rise significantly, and rumours of a transfer circulate. Real Madrid and Liverpool, also on the lookout for left-backs this year, are rumoured to be interested too, despite Moreno signing a new deal in October to stay at Sevilla until 2018.
Another young Spaniard who has impressed in La Liga this year is Valencia's Juan Bernat. Taking over from Jordi Alba, who moved to Barcelona in 2012, Bernat is like his former mentor in the sense that he is a winger turned fullback, and therefore possesses outstanding pace, crossing and ball control. The last year has seen him collect 6 Under-21 caps while appearing 37 times for Los Che. May be the least costly option of those on this list, while also being a player of great potential.
