Tottenham Hotspur are believed to be interested in signing Benfica's attacking midfielder Nicolas Gaitan as manager Ander Villas-Boas looks to add yet more depth to his already impressive squad.

Portuguese newspaper A Bola reports that Villas-Boas has been monitoring the performances of Gaitan this season as he considers making an offer in the new year.

Spurs already have an array of talent in midfield but few have experienced regular success and featured heavily in the Champions League.

Christian Eriksen is one of the few to win major trophies and regular compete in Europe and it appears Villas-Boas may well feel his side needs more experience as he seeks to secure a top four finish.

The Argentina international has been tracked by Manchester United for some time but has remained at Benfica and has been a regular starter once again this season both domestically and in the Champions League.

Should the 25-year-old be presented with the opportunity to join Tottenham then he would be linking up with international colleague Lamela who has yet to demonstrate his best form for the north London club.

The left winger became Tottenham's most expensive ever signing when he joined from Roma in the summer but he has admitted that he has found it hard to adapt to life in the Premier League.

"I think I need a bit of time," Lamela told the Evening Standard. "I feel good here, although getting used to life here in every sense is a completely different thing. I've barely been here two months, so time is maybe what I need.

"I need training, a bit of rhythm, some games. English football is very different from the game in Italy - much more physical, whereas Serie A is more tactical. It's not necessarily more difficult, but it's just different. This is a style of football I like very much, though, and I think, with the way I play, it will be very suited to my game."

Spurs fans will be keen to see the best of Lamela, who scored 15 league goals for Roma last season, especially having witnessed their side score just nine goals in nine league games.
