Just after four months of playing at Aston Villa, Youri Tielemans wants to leave the team. He left Leicester and joined Aston Villa but this 26-year-old palyer couldn't have too much chance in Aston Villa to prove himself and so far in this season he played in eight games for Aston Villa but he was never in the first squad and that's why he doesn't have a good relationship with the coach of Aston Villa and he wants to leave during the winter.
Emery I believe is not the perfect coach to unlock his potentials. Youri would have been a better option for Pep Guardiola replacing Gundogan and he was also a player on free transfer.
If he doesn't have enough game time, then its time to work hard be consistent and when the opportunity comes up again, he will be lined up for the spot.
I watched him play for Leicester City so it bothers me to see such a talented midfielder on the bench.
This will not be how he ends his career, he should consider a move out with his agency.
