Tottenham are set to go head to head with Liverpool to sign Argentine striker Lucas Alario, according to a report.

The Sun claim that Spurs are interested in signing Alario despite him signing a new contract with River Plate that keeps him with the Argentinian side until 2020.

It is said that Liverpool have previously had an £8.5million bid rejected for the forward but remain interested, while Tottenham are also monitoring him.

The report details that Alario has a £15.2million release clause in his new deal and that Italian duo Torino and Inter Milan are also keeping tabs on the 23-year-old.

Alvario’s agent Pedro Aldave claimed that his client would have moved to White Hart Lane in July if his old £11.3million release clause was met, but the London giants will now have to cough up extra money to land the newly-capped Argentina international.

Any deal for Alario is likely to be complicated one as third-party ownership issues need to be resolved before the front man could move on.

Alario has scored an impressive 19 goals in just 40 appearances for River Plate but is yet to play in Europe.

Spurs were linked with several forwards in the transfer window and did manage to land Vincent Janssen to support the club’s talisman Harry Kane. They are the only two senior striker options in Mauricio Pochettino’s squad.

Spurs’ success last season means that they will be competing in both European and domestic competitions, so Pochettino’s squad is likely to be stretched.

In other Tottenham transfer news, their defender has agreed a new £75,000-a-week deal with the club.
