Newcastle goal hero Matty Longstaff has been pictured in a Celtic jersey alongside brother Sean in a brilliant throwback snap.

Longstaff, 19, scored the winner for Steve Bruce's men on his debut at St James' Park yesterday afternoon.

The strike will live long in the memory for the young Geordie who played alongside his brother in the middle of the park for their boyhood heroes.

But a photo which emerged on social media following the three points against the Red Devils could prove that it was in fact Celtic who were youngster Matty's favourites.

Shared online by Stan Collymore, the ex-striker said: "Great picture of the Longstaff brothers, I particularly like Matty's threads..."

The pic racked up thousands of likes and shares with fans of both the Hoops and the Magpies lapping it up.

One joked: "My favourite all time Newcastle player now".

Another added: "I knew I always liked them!"

A third said: "I knew it!!! I said yesterday them two lads are definitely Celtic fans".

It has since been claimed that Celtic hero and former midfielder Alan Thompson is the uncle of the two lads.
