Luke Shaw's Manchester United future is in doubt following further public criticism from Jose Mourinho.
The 22-year-old joined from Southampton in 2014 in what was then a world-record deal for a teenager, fresh from being named in the PFA Team of the Year and becoming the youngest player at the World Cup in Brazil.
But four years on Shaw has fallen down the pecking order with England having struggled for game time at United, thanks in no small part to an inability to win over Mourinho.
The pair have endured a strained relationship since the Portuguese was appointed in 2016, with the latest low coming in Saturday's 2-0 FA Cup quarter-final win against Brighton.
Shaw was hauled off midway through the win - a move that is understood to have annoyed the left-back, with that anger fuelled by Mourinho's criticism.
"I had to change one (full-back) and I chose Luke because at least Antonio (Valencia) was capable of good positioning defensively," Mourinho said. "Luke, every time they came in his half, the cross came in."
It is not the first time Mourinho has publicly criticised Shaw, only strengthening his desire to kick on and prove his worth.
But he is now understood to be reassessing his future - just a month after the United boss suggested a new and improved deal could be deserved for a player whose contract expires next year.
Shaw was linked with a move last summer but stayed put as he recovered from ligament damage until belatedly making a first start of the season in December.
The United hierarchy are believed to want Shaw to stay but this latest flare-up is only pushing him closer to the exit.
He has been regularly linked with a move to Tottenham, where he would re-join his former Southampton boss Mauricio Pochettino. Chelsea, the club Shaw grew up supporting, are also understood to be interested.
