Adam Lallana says England team-mate Dele Alli has quickly become "a magnificent player for England", but says he must be given time to develop.
The midfielder has emerged as a star for Tottenham over the last two seasons and impressed for England in their friendly defeat to Germany.
And Lallana is in awe of the 20-year-old and his mentality.
“Del is a fantastic player,” he said. "He is already a magnificent player for England.
“He is special. I love the way he goes about his business: No fear. He’s brave.
“But still people need to be patient with him. He is still a young boy and performing how he does is way above his years.
“He is not even 21 yet. It is important that we don’t get carried away."
Alli has been criticised for being sent off in Tottenham's Europa League game against Gent, ending with Mauricio Pochettino's side crashing out. He has been booked five times in all competitions, but Lallana says he has no need to lose his tendency for winding opponents up.
“That’s what makes him Dele. All players have different attitudes that make them what they are and that’s why he is unique and a special talent.”
“I think Dele Alli is one who is psychologically strong.
“He’s young, but you can groom him into being England captain. He’s going to be a top player, and the armband might give him some responsibility.
“Dele is still growing up and learning the game, which is why he does the odd silly thing. Giving him the captaincy would help him grow up faster, and cut out a bit of the petulance.
“I don’t think he should be captain now – Gary Cahill is the obvious choice for the next World Cup – but one day I could see it really bringing the best out of him."
