Son Heung-min has claimed that Tottenham Hotspur's "unbelievable" run in the Premier League has changed the mentality of the squad.

Spurs are unbeaten in their last 13 league games and currently sit just four points behind leaders Manchester City in fifth place.

Despite the confidence surrounding the club, Son claims that complacency will not be an issue ahead of Saturday's meeting with West Bromwich Albion.

"The run is unbelievable – it's very good for us, it gives us a good mentality," the 23-year-old told the club's website.

"Every game we play we want to continue the story. We'll try in the next game to keep the run going.

"It won't be easy but we want to win at West Brom – we didn't win against Chelsea last week which meant I was disappointed but that's football. I always want to win."

Spurs could move up to third if results go their way this weekend.
