Pau Lopez is on stand-by for a first Premier League start for Tottenham with doubts over first-choice goalkeepers Hugo Lloris and Michel Vorm.
Lloris missed the 3-1 victory over Swansea on Wednesday after being struck down by a virus and is still being monitored ahead of the home match against Watford on Saturday.
Vorm, meanwhile, has a knee problem and is almost certain to miss the game. Lopez is a 22-year-old Spanish goalkeeper who is on loan from Espanyol.
Lopez was Espanyol's first choice keeper in La Liga last season and also made Vicente Del Bosque's preliminary squad for the 2016 European Championship.
