Tottenham defender Jan Vertonghen was impressed by his young teammates in their Capital One Cup win at Carlisle United.
Ryan Mason and Adam Smith started the game at Carlisle, and Spurs defender Vertonghen was impressed with what he saw.
"The guys who played are real quality players, very skilful and with a good mentality," said Vertonghen, who signed from Ajax in the summer.
"I think that Ajax, for young players, is one of the best clubs in the world at which to develop, so I know good young players and we have them here at Tottenham.
"What I have seen here makes me think that all these players can eventually play for the first team."
