Manchester United are having doubts as to whether Everton left-back Leighton Baines can be Patrice Evra's long-term replacement at Old Trafford, reports The Daily Star.
According to reports in Spain, the Red Devils are now searching for an alternative to the England international as they believe he may be too old to act as the long term solution to United's left-back position.
Baines, who is 28-years-old, was the subject of interest from the Premier League champions throughout the summer as David Moyes tried to bring with him to the Theatre of Dreams.
However, United failed in their pursuit of Baines and only managed to bring in his teammate Marouane Fellaini.
And it had been reported that Moyes would bring Baines to United in January for £15 million, however any potential deal for the Toffees ace may now be off.
Baines has been in fine form so far this season and is currently on international duty with England.
