Niasse has been added to the game with a £5.0m price tag and gives managers a fresh, low-budget forward.
Tomer Hemed (£5.0m) is another cut-price player making a claim for recognition.
He took his tally to two goals and an assist from his last three Gameweeks in Sunday’s 1-0 win over Newcastle United.
Hemed, of Brighton & Hove Albion, has scored or assisted 20 goals in his last 23 starts at the Amex Stadium.
But managers will wait to hear of any possible retrospective action for a coming-together with DeAndre Yedlin (£4.4m).
