Will Grigg has just five goals in his first 20 Sunderland appearances.
Grigg almost guarantees goals in the third tier, and when Sunderland bought him in January there was an expectation that he would be the man to fire them to promotion.
However, Grigg hit just five goals in 20 appearances for Sunderland and really struggled at the Stadium of Light.
The Black Cats also fell short, as they were beaten 2-1 in the play off final by Charlton.
And Grigg said: “This is the first time I’ve fallen short in this league, it’s been a disappointing season for myself and I want to make sure it doesn’t happen again next season.”
Sunderland’s failure to earn promotion has led to current boss Jack Ross being put under serious pressure.
Stewart Donald has suggested he will keep the Scottish boss for next season, but Ross will simply have to start well.
If Grigg can hit form then it would be a boost to Sunderland, who struggled to find a reliable goalscorer last term, after Josh Maja left.
