Tottenham manager Antonio Conte has confirmed the club will be active in the January transfer window.
Spurs, who resume their Premier League campaign against Brentford on Monday, went into the World Cup break fourth in the standings but Conte has earlier said there is still a gap between them and their rivals when it comes to squad depth.
Sporting right-back Pedro Porro has been linked with a move to north London, as well as Fiorentina midfielder Sofyan Amrabat, who was close to a switch earlier this year.
"If there is the opportunity to strengthen the squad, we’ll do something. You know what is our politics and we try to follow these politics and to improve the team," Conte told reporters on Friday.
"The politics is about young players with not big salaries. We have to sign players that they can stay in our vision of the club here.
"Otherwise, we’ll continue with these players. I’m happy with them."
