Mexico coach Luis Fernando Tena has urged Giovani dos Santos to resolve his future at Tottenham, with the playmaker in need of regular games.
The 23-year-old has endured a frustrating time at White Hart Lane since completing a high-profile switch from Barcelona.
His ability remains unquestioned, but Harry Redknapp's reluctance to offer him opportunities to shine in England has held him back.
Dos Santos offered another timely reminder of what he is capable of on Sunday as he stepped off the bench to net twice for his country in a 2-0 victory over Gabon at the 2012 Olympics.
His international coach now wants to see the youngster make a definitive decision on where his footballing future lies, with reports continuing to suggest that he could soon be heading back to Spain.
Tena said: "Giovani proved he is getting better football-wise. He made an impact again from the bench and he has done well throughout this competition from the bench.
"He showed great quality. Sometimes we don't finish but fortunately today we took two of the chances thanks to Giovani out of the many we made.
"Giovani had to improve physically because he came from vacation into the group after everyone else.
"But he is doing well, working in morning and afternoon training sessions with the physical coaches.
"If he keeps improving, he will get a chance [to start]."
But Tena added: "He definitely needs to find his rhythm. He has the potential to achieve things and it would be better if he had that rhythm at club level.
"Unfortunately he doesn't get that many minutes on the pitch at Tottenham.
"It will be better if he played more at club level and then he can give more to Mexico."
