Norwich City's club record signing Ricky van Wolfswinkel has reportedly pricing himself out of a return to Sporting Lisbon.

Portuguese sports paper, A Bola, reported on Wednesday night discussions between van Wolfswinkel and his old club had now stopped after the parties were unable to agree on the striker's salary demands.

The Dutchman and his advisor, Louis Laros, arrived in Lisbon on Tuesday to conclude a potential transfer after City and Sporting had reached an agreement for a deal in the region of £4m.

Earlier reports in the Portuguese media on Wednesday afternoon claimed van Wolfswinkel was looking for an annual salary of between £1.5m and £1.8m to cut his ties with the Canaries.

Van Wolfswinkel still has two years left on his current Carrow Road contract but appears to play no part in Alex Neil's first team plans after spending last season on loan at French Ligue One club St Etienne.

The frontman moved to Norwich from Sporting for an initial reported fee of £8.5m in 2013 but scored only one goal in 27 appearances during a season which ended in relegation from the Premier League.
