Mauricio Pochettino was full of praise for Son Heung-min after his winning goal against Crystal Palace, but played down fears over Harry Kane.
South Korea international Son scored the only goal of the game against Palace in the second half, capping an impressive performance from the summer signing on only his second Premier League start.
Pochettino has previously earmarked Son as a potential central striker to take the goal burden off Harry Kane, and the Argentinean saw more positive signs from Son at White Hart Lane.
“It was one of the best performances of the season,” Pochettino said. “We thoroughly deserved the result.
“When you sign players you expect them to make a big impact in the team. We are very happy with him [Son].
“He has adapted to the team very well. After scoring twice in the Europa League he scored again and when you arrive at the club as a striker that’s very good.
Asked about Kane, who continues his search for a goal at club level this season, Pochettino responded: “I am not concerned [about Kane]. Maybe he is a little bit because he’s a striker but it’s only a matter of time before he scores again.”
