The 25-year-old could face West Brom in the Premier League this weekend.
Indeed, Everton boss Roberto Martinez has confirmed the 25-year-old 'could' feature for the Merseyside outfit this weekend, according to Sky Sports, and he'll hope it adds further dynamism to a strikeforce currently doing very well.
Everton were in a woeful run of form but put a stop to that last week and just two good results have rocketed the Toffees up to eighth in the standings.
Martinez's men are now just six points off fifth, although the top four looks far too ambitious at this stage.
Here, meanwhile, is how Niasse looked in training - can he make an impact at Goodison Park this season?
