#4 Thorgan Hazard

Thorgan Hazard is Eden Hazard's younger brother. His form for Monchengladbach has been consistent since he joined them and he has also impressed scouts of major sides across Europe. There were reports that Chelsea were willing to bring back the younger Hazard but there has been no movement on that front.
Hazard was commendable in the league with 6 goals and 4 assists, but it was in Europe that he sparkled last season providing four goals and three assists in eight appearances.
Gladbach used to be a top side back in the '70s and are slowly building a good side that can qualify for the Champions League consistently. If they can manage that, the younger Hazard could soon face the club that that let go of him.
Hazard has already made 5 appearances for the senior Belgium team as well.
