Tottenham are poised to submit an improved bid for Espanyol goalkeeper Pau Lopez within days, according to a report.

Spanish outlet AS claim Spurs will imminently up their initial £1.7million offer for the 21-year-old but the Spanish club will refuse to sell unless the Londoners meet his £13million release clause.

Tottenham are set to increase their offer for Lopez after it emerged on Tuesday that Hugo Lloris will be sidelined for a month with a hamstring.

Spanish outlet Sport claimed at the start of August that the Londoners had a £2million bid for the Spanish shot stopper rejected as manager Mauricio Pochettino looked to add competition for established No1 Lloris.

The injury to the Spurs captain increases the need to sign a new keeper even though his deputy Michel Vorm is an experienced Premier League campaigner.

Lopez made his debut for Espanyol in 2014, a club previously managed by Pochettino.

Lopez made 38 appearances for the La Liga club last term, as he conceded 74 goals, which included seven clean sheets.

This is in stark contrast to Lloris, who kept 13 clean sheets and a league low of 35 Premier League goals conceded for the 2015-16 season.

Pochettino’s ties with his former club could help smooth out the deal as the Argentine boss looks to add his third major signing of the summer.

Spurs finished an impressive third last season which secured them Champions League football, but they stuttered in their 2016-17 season opener – drawing 1-1 with Everton at Goodison Park on Saturday.

In other Tottenham transfer news, they are told to up £3million bid for English wonderkid.
