Lucas Torreira (Arsenal)
The 22-year old midfield battler who impressed at the World Cup is what Arsenal has been crying out for years. Torreira is a ball-winner who loves the dirty side of the game and is already a fan favourite in North London.
So far this season he has shown that he can score goals too, a famous strike versus London rivals Tottenham just increased his value to the fans and an acrobatic winner at home to Huddersfield sent the Emirates into hysteria.
And there is still more to come from the midfielder. His free kick potential and long-range shooting ability have not yet been realised and these weapons could show their faces to Arsenal supporters before season's end. Easily one of the first names on the Arsenal team sheet in his first season the Uruguayan is looking like money well spent and more.
