The forward completed a move to Celtic Park this week, and has been compared to the Everton and Belgium striker by his former Fulham boss.

The former Fulham manager and defender had hugely encouraging words on the Bhoys' new signing, recently signed on a four-year deal, who he helped bring into the first team during his time in charge at Craven Cottage.
Symons managed the Cottagers from September 2014 until November 2015, and though Dembele was used sparingly initially by the Welshman, he took his biggest steps under his tutorship, which saw him win a regular spot and score five times in the league last October.
But it is Symons' comparison of Dembele to Belgium and Everton star Romelu Lukaku that is sure to really excite Celtic supporters.
"He's a little bit like a young Romelu Lukaku when he first came to Chelsea," Symons told Sky Sports.
"If you look at his attributes as a player, he's got everything that the top teams are looking for."

Lukaku was also a supremely talented young forward, exploding on to the scene for Anderlecht and Belgium aged just 16, before earning a big money move to Chelsea in 2011. He never really got much of a chance at Stamford Bridge, but his goal records in a loan spell at West Brom and Everton earned him a permanent switch to Goodison Park, and the striker is now being talked of as one of Europe's top strikers after a season where he scored 25 times.
Dembele, who scored 17 times for Fulham last season, is a similar talent according to Symons
"He needs to be pushed a little bit but he could go on to emulate what Lukaku is doing now," the 45-year-old added. "I believe that.
"He's got pace and he's a threat over the top, but he's also got the power and strength to play as a lone striker and hold the ball up. He can play as a one or in a two and he scores goals. Everything is geared up for him to be a top footballer."
