Alli appears to have been rejuvenated under Jose Mourinho, having scored twice in the 3-2 win over Bournemouth, while he was also on target in the 4-2 defeat of Olympiakos in the Champions League.
But Mourinho also hinted at the need for the England international to be properly motivated in order for him to achieve his full potential.
“I think Dele Alli can do anything he wants. He has the right age and experience, playing Champions League and [for the] national team.
“He has everything - it is just a question of motivation. This is not just the individual, this is everyone."
