In truth, all three clubs could do with a reliable centre-forward. The Saints have signed Che Adams and Danny Ings on a permanent basis but Ralph Hasenhuttl might need more than a converted winger and an injury-prone 26-year-old if he wants to lead the South Coast club into the top half of the table.
Brighton, meanwhile, continue to be worryingly reliant on the veteran Glenn Murray while Crystal Palace desperately need to replace Michy Batshuayi after the loanee returned to parent club Chelsea.
Fortunately, Ghana international Diagne wants to swap Turkey for England, just six months after joining Galatasaray from Kasimpasa for £11.5 million.
A prolific goalscorer, Diagne netted 31 times in all competitions last season, transforming Gala’s season and firing the Istanbul giants to a second successive Super Lig title in May.
At 27 and with spells in Hungary, France, Belgium and China under his belt, Diagne has enjoyed a nomadic career so far but he has earned the chance to really establish himself in a top league after a couple of outstanding years in front of goal.
