Portuguese looking to strengthen in next five days.
Tottenham head-coach Andre Villas-Boas says he wants to sign a midfielder before the end of the month.
The Portuguese is keen to add more creativity to the middle of the park, with Luka Modric expected to seal a £33m move to Real Madrid this week.
Spurs have already allowed Niko Kranjcar and Steven Pienaar leave the club this summer, while Tom Huddlestone is expected to move to Stoke City on loan in the next few days.
“The market can be frenetic in the last few days so anything can happen,” Villas-Boas told Sky Sports.
“We are still looking to strengthen our squad with a midfielder so let’s do the deals that we have to do.”
Spurs have been linked moves for Porto Joao Moutinho, Willian of Shakhtar and Malaga playmaker Isco.
The club have also reportedly bid for Rennes star Yann M’Vila although Villas-Boas has said the enforcer lacks the flair required to replace Modric.
