The French attacker has joined from Sporting on a year-long loan.

New Leeds United forward Hadi Sacko has wasted no time in joining up with his new teammates, with the Whites' Twitter account picturing him in training gear giving the thumbs up at Leeds' Dublin hotel.
The versatile Frenchman seemed like he had been involved in pre-season training on Tuesday, just a few hours after Leeds announced the deal, and will now crack on with the rest of Garry Monk's squad in their pre-season camp ahead of matches against Shelbourne and Shamrock Rovers.
The 22-year-old is Leeds' third signing of the summer after striker Marcus Antonsson and defender Kyle Bartley, and is on loan at Elland Road until the end of the season, when they can make the deal permanent if they wish.
The former France Under-20 player made his debut in the Europa League at just 18 years old, while still at Bordeaux, and would go on to accumulate several appearances over two seasons with the Girondins.
Sacko went on to join Sporting in 2014, and last season took in a loan at Sochaux in Ligue 2, where he played both wide right and up front, aside from plenty of football at the Portuguese giants' B side.
Sacko will likely now contest for a wide position at Elland Road, as he seeks to earn a transfer to Yorkshire.
