Pundit and former Chelsea and Aston Villa striker Tony Cascarino has told The Times that Manchester United outcast Luke Shaw will “regret staying” at the club and he should look to leave as soon as possible.

The 22-year-old has struggled to win over Red Devils boss Jose Mourinho over the course of the last 18 months, and he found himself behind the likes of Ashley Young, Matteo Darmian and Daley Blind in the pecking order for the left-back and left wing-back roles earlier this season.

It looked as though things may be changing for Shaw when he made his first Premier League appearance and start of the campaign in the 1-0 win against Bournemouth at Old Trafford last Wednesday, putting in a man of the match performance.

However, the England international found himself back on the substitutes’ bench for the 2-1 win against West Bromwich Albion at the Hawthorns on Sunday, with Young and then Marcos Rojo both featuring at left-back before him as he failed to come on.

In his column for The Times, Cascarino said: “He needs to leave Manchester United and restore his reputation as a top-flight left back. A footballer’s career is not long and he can’t waste his talent sitting on the bench — even if he will earn more money doing so

“Shaw will regret staying at United.”

Manchester United have been heavily linked with a move for Tottenham Hotspur’s Danny Rose over the last couple of months, and if that deal does materialise during the January transfer window then you would think that Shaw’s career at Old Trafford is done.
