Heung-min Son reacts to miss v Honduras in Olympic Games quarter-final
Tottenham winger Son Heung-min has been made available for their home match against Crystal Palace following his exploits at the Olympic Games in Brazil with South Korea.
The 24-year-old was one of his country's designated over-age players as South Korea made it to the quarter finals before losing 1-0 to Honduras, on the same day that Spurs drew 1-1 away at Everton on the first day of the new Premier League season.

Son scored twice in the group stage as countries can field three players over the age of 23 in the Olympics, but has returned to Spurs in time for Saturday's fixture against Crystal Palace.
Manager Mauricio Pochettino told the club's official website: "Son is available, he arrived a little bit sad after the elimination in the quarter-final and we’ll see.
"We need to assess him tomorrow and we’ll see if he’s in the squad or not."

The former Bayer Leverkusen forward has happy memories of Crystal Palace visiting White Hart Lane, as it was his goal that sealed victory against Alan Pardew's side, coming off the bench to score in the 1-0 win back in September.
But Son had a difficult first season in English football with just four Premier League goals to his name, often fielded out of position as a lone striker when Harry Kane was rested.
He still made 42 appearances for Spurs last season, scoring eight goals, but will be itching to get back into the first-team fold and show why Pochettino paid over £20m to bring him from the Bundesliga to England.
In other first team news, Mousa Dembele remains suspended while Hugo Lloris is set to miss four weeks after picking up a hamstring injury in last weekend's draw at Everton, with Pochettino confident the Frenchman will return after the international break.
