Tottenham fullback Alan Hutton says they must be wary of Europa League opponents Hearts.
Hearts host Spurs in the Europa League play-off first-leg, with the Premier League side favourites to progress.
Former Rangers defender Hutton said: "I've warned everyone about what it's like so no one is going up to Scotland thinking it's going to be an easy game.
"Tynecastle can be an intimidating environment - the fans are close to the pitch which creates an intense atmosphere.
"In some ways it's actually quite like White Hart Lane.
"It's going to be a tough test for us - and no one down here is treating it lightly.
"The boys will need to be on their game in the first leg or Hearts will punish them.
"But, trust me, the boys are right up for this game."
