Dos Santos unhappy at not playing more at Spurs
Mexico forward Giovani Dos Santos says he is becoming increasingly frustrated with his lack of opportunities at Tottenham and may leave the English Premier League club when the transfer window opens in January.
A regular for Mexico, Dos Santos starred as the team successfully defended its Gold Cup title against the United States in June.
Those performances followed a successful period on loan at Spanish club Racing Santander during the second half of last season, scoring five goals in 15 matches.
Nonetheless, Dos Santos has failed to break into Tottenham manager Harry Redknapp's starting lineup.
Dos Santos says he wants ''more minutes'' on the pitch and has had ''lots of offers'' to leave.
