Kevin Phillips has insisted that it would be “best for all parties” if big-earning Sunderland striker Will Grigg left the club.

Speaking exclusively to Football Insider, the ex-England striker claimed that things haven’t worked out for the hitman on Wearside, and that it may be time for him to seek a new challenge elsewhere.

The Northern Irishman arrived at the Stadium of Light from Wigan Athletic for a fee of around £4million on deadline day last January, but has struggled to make a consistent impact for the Black Cats.

The 28-year-old has hit just eight goals in 48 appearances for the Wearsiders, with just three in 26 outings this term.

Black Cats manager Phil Parkinson has not ruled out the possibility of Grigg leaving the Stadium of Light during the current transfer window, and Phillips believes that his exit could be a wise move for all involved.

When asked whether it was time to cash in on the striker, the ex-England international told Football Insider: “It just hasn’t worked out for him, has it?

“Sometimes it doesn’t work out, I thought it was a good signing at the time – again another player we looked at at previous clubs I was at.

“I thought League One would have suited him down to the ground but it just hasn’t worked out, he obviously came for big money, in terms of his salary and that, if they could ship him on and free some money up to strengthen in other places then maybe that would be best option for all concerned.

When asked if the Black Cats would have to take a big financial loss on the fee they paid for Grigg, Phillips added: “Yeah, of course, for any club, certainly in League One, that’s big, big money so the lad himself will be disappointed it hasn’t worked out and as I say, probably best for all parties if they parted ways and they could use that money somewhere else.”

Grigg registered 65 goals in 150 appearances for previous club Wigan, and finished the 2015/16 season as the top scorer in League One with 25 goals.

This term, however, he has fallen beneath Charlie Wyke in the pecking order at the Stadium of Light, and has not started a match since the 1-0 defeat to Gillingham on December 7th.

In other Sunderland news, Kevin Phillips believes that this Black Cat can become a club legend if he fires the Wearsiders to promotion this season.
