Tottenham boss Andre Villas-Boas has blamed the language barrier for Erik Lamela's uninspiring performances.
The Argentine international arrived at White Hart Lane in the summer for a reported club record fee of £30m.
He has, however, played an insignificant part in Tottenham's season thus far and is still waiting to start his first Premier League game.
Lamela was an unused substitute in the 1-0 against Hull City on Sunday night and has only been given sufficient game time in Europa League games.
Falling behind the likes of Andros Townsend in the pecking order, questions over his price tag are becoming more prominent.
Villas-Boas believes that Lamela's slow start is down to the fact that the 21-year-old doesn't speak English.
Asked by reporters whether he thought Lamela was being affected by his price tag, Villas-Boas said: "Not really, no.
"We have been speaking a lot with him. I think getting acquainted to the Premier League is important but he doesn't know the language."
AVB says that other signings, such as Roberto Soldado, have bedded in quicker because of their knowledge of the English language prior to their arrival at White Hart Lane.
He also said that Lamela is producing half of what he is capable of and must understand that competition for places is high at Spurs.
"Soldado had some knowledge of the language before so it was a little bit easier for him," the manager said.
"With Erik it was a little bit more difficult but we have given him massive, massive help and his family arrived this week.
"He knows he isn't producing half of what he can produce but he understands the situation now is that he has to compete for his place."
