(Reuters) - Tottenham Hotspur captain Son Heung-min has emerged as a natural leader after high-profile departures at the Premier League club and consistently delivered fine performances this season, manager Ange Postecoglou said on Monday.

Son, Spurs' top scorer this campaign with 15 goals and eight assists, took the captain's armband after Tottenham's record goalscorer Harry Kane moved to Bayern Munich last year.

Spurs also lost France's World Cup-winning goalkeeper Hugo Lloris, who joined Major League Soccer club Los Angeles FC after an 11-year stay in north London.

"It wasn't a big decision (on making Son the skipper)," Postecoglou told reporters before Tuesday's trip to West Ham United.

"With Hugo being a huge influence and Harry as well, Eric Dier too — there are others who have been at the club a long time. Part of it all along was that I felt like we needed to make a change to show we are going in a new decision.

"I felt Son was a natural and he has been a leader within his national team. I had no hesitation putting him in that position. Sometimes when you get the official title it can be a burden, but his performances have been outstanding."

The Australian coach's attacking philosophy has won much praise since he took the Spurs job in June and his team led the standings after going unbeaten in their first 10 matches.
