But Vlaar says: When he comes on he always tries to make a difference.
The Champions League is something he must want to play in. Villa have a big squad and a lot of players have played a role through the season.
It would be nice for them to continue together and make some improvements to the team to make it even better and keep going."
Vlaar continued: Duran has scored important goals throughout the season now he has two in short notice.
He is still only 20, so he is still a very young player. To be behind Ollie Watkins at that age is nothing to be ashamed of.
Everybody knows how great Emery is, even from his past. He has proved what a great coach he is at other clubs as well.
Wherever he is he makes players better and improves them. I don't think many players will want to leave Aston Villa while he is here."
