#3 Thomas Lemar (Monaco, France)

It was a hugely successful season for Monaco as they beat Paris Saint-Germain to the Ligue 1 title, and lost to Juventus in the Champions League semifinal.
Thomas Lemar was at the heart of Monaco's midfield/wing play throughout the season. He can play anywhere in the midfield (central, left or right).
Arsenal bid a whopping £92 million for him during the summer, but the deal fell through. In 2016/17, Lemar scored 11 times and assisted 14 more from midfield. Still only 21, he is pacy and a good dribbler.
He was called to the French team for the FIFA World Cup qualifiers, where he scored 2 times and assisted couple more. Given his performances and impact, Lemar's omission from the list came as a surprise to many.
