Sources: Sunderland striker Wyke tells Celtic he wants four-year deal and big signing-on fee

Charlie Wyke has told Celtic he wants a four-year contract that will double his wages, Football Insider understands.

The Sunderland striker has held talks this month with the Glasgow giants over joining on a free transfer.

A Celtic source has told Football Insider that Wyke is holding out for a long-term deal running until 2025 that would include a pay hike doubling his Black Cats deal.

The 28-year-old also wants a multi-million pound signing-on fee.

Sunderland have already offered Wyke a new and improved long-term deal but he has yet to accept it.

This site revealed last week that the centre-forward is “very keen” to swap the League One big hitters for Parkhead.

The centre-forward position is one of some concern for Ange Postecoglou’s side ahead of next season.

The Hoops sold Polish striker Patryk Klimala to New York Red Bulls in April.

Star man Odsonne Edouard also looks to be headed for the exit door amid interest from multiple Premier League clubs.

Meanwhile, long-serving Leigh Griffiths is out of contract at the end of the month and there has been no official word on a new deal.

If all three were to depart it would leave Albian Ajeti, who scored just once in his last 20 appearances last season, as the club’s only senior striker.

Wyke is a proven goalscorer and his 53 matches in all competitions last season yielded 30 goals.

He has found the back of the net 58 times in 175 appearances in English football’s third tier across spells with Hartlepool, Bradford and Sunderland.
