Could changes be due at Tottenham behind Hugo Lloris?
Lopez spent the 2016/17 season on loan at Spurs and while he did not play a game for the first team, the Espanyol stopper is claimed to have found the experience valuable.
Lopez is out of contract at the end of the season, and his former manager suggested earlier this month that he could head back to Tottenham.
Ex-Espanyol boss Sergio Gonzalez told Tutto Mercato Web: ""Without a doubt, Pau has a great future ahead of him, whether he is at Espanyol, in Italy or again at Tottenham, I wish him the best decision for his career.
"Pau has to do what he feels inside… certainly going abroad does not intimidate him, as he showed during the loan, despite the fact that he has never played. The Premier League experience was fundamental, Lopez grew up again and Spurs goalkeeping coach Toni Jimenez gave him valuable advice."
Tottenham would still be looking at keeping Hugo Lloris as first choice next season.
Lopez could easily replace Vorm as second choice, battling with Paulo Gazzaniga for that place, and Tottenham would be better off, no longer relaying on a goalkeeper in his mid-30s as a back-up.
