Lopez has spent the season on loan at Tottenham Hotspur from Espanyol.

Tottenham Hotspur are confident Espanyol will accept their offer for on-loan goalkeeper Pau Lopez - despite it being around £4.25 million short of the £6 million option they had in place in January, the Guardian reports.
Tottenham are said to have passed up the opportunity to buy Lopez outright, believing they could get him for a lower price.
And it is claimed that the Premier League runners-up have since lodged a bid of £1.75 million, with another £1.75 million potentially due in add-ons, along with a cut of any future sale.

Lopez failed to appear competitively in his season at White Hart Lane, despite being Espanyol's first choice throughout the 2015-16 campaign.
However, the Guardian reports that the Spaniard remains highly rated by Spurs head coach Mauricio Pochettino, and the feeling - it seems - is mutual, with Lopez "not inclined" to extend his Espanyol deal which expires next summer.

And that is said to have left Tottenham believing they are in a strong negotiating position, as they seek to back up experienced pair Hugo Lloris and Michel Vorm.
Recruiting Lopez permanently could enable Luke McGee to return to Peterborough United on a full-time basis, after the League One side admitted their interest in the 21-year-old last month.
