Tottenham are studying a move for £35million-rated Benfica midfielder Gedson Fernandes.
Manchester United and Spurs' Champions League Final opponents Liverpool have already been linked with the young star of Portuguese football.
But the north Londoners are now making the bigger play to land the 20-year-old enforcer and have moved ahead of their top-six rivals in the queue.
Representatives working for Fernandes were in England last week and met with potential suitors.
Tottenham boss Mauricio Pochettino has been told by chairman Daniel Levy that he will have money to spend this summer after they made no new signings in the last two transfer windows.
