Erik Lamela has gone from serial underachiever to a real man during his three seasons at Tottenham.

That is the verdict of former Spurs defender Graham Roberts, who has been impressed by how the Argentine has developed in the current campaign.

Lamela has established himself as a first-team regular in the team that has fallen narrowly short in their Premier League title quest.

The north Londoners lept slip a two-goal lead to draw 2-2 against Chelsea on Monday night, which enabled Leicester to secure the title for the first time in their history.

Lamela has scored 10 goals in 42 matches in all competitions for Spurs this season, 35 of which he has started, and has leapfrogged above the likes of Nacer Chadli and Heung Min-Son in the attacking midfield pecking order. The 24-year-old has also supplied nine assists, eight of which have come in the Premier League.

Roberts took to Twitter on Tuesday to express his admiration for the improvement of the Argentine.

Lamela had a difficult 18 months at White Hart Lane after signing from Roma in a deal worth up to £30million in the summer of 2013.

He struggled with the language, culture and physicality of the Premier League but has come on in leaps and bounds under the guidance of countryman Mauricio Pochettino.

In other Tottenham news, Therry Henry has claimed the club will be able to lure some big-name signings to White Hart Lane in the forthcoming transfer windows.
