#3 Breel Embolo (Schalke)
It is easy to forget that Embolo is still only 21. He has been playing regular first-team football for four years, and has been a key player for the Swiss national team over much of the same period. He initially made his name with his first club, Basel, with whom he was a part of some impressive Champions League displays, including in the 2014/15 season, where they progressed from a group including Real Madrid and Liverpool.
He left Switzerland in 2016, and moved to Schalke, where his career has been halted slightly by injuries. He has appeared just 28 times in the Bundesliga over the past two years, and scored just five goals. He will go into this season fully fit, meaning he can finally begin to make his mark in the Bundesliga. He is a strong, powerful striker, with the pace to cause problems for defenders. He will hope to add more goals to his game, and if he can do so, he will be a top striker.
