Videos have emerged of former Tottenham manager Mauricio Pochettino celebrating in the BBC Sport studio as Heung-min Son provided a last-gasp assist to give South Korea a crucial win and help them qualify for the knockout stages of the World Cup.

At club level, Son has endured a difficult first half of the season so far for Spurs, with just five goals in all competitions before the international break (Transfermarkt).

The 30-year-old has been far from his best and has failed to recapture the form that won him the Premier League Golden Boot award last season.

Son missed the last three games for Spurs before the break, having suffered a fractured eye socket in the Champions League game against Marseille at the start of November (Telegraph) and it was unclear at the time whether he would make the World Cup in Qatar.

After a successful surgery on his eye (Telegraph), Son made Paulo Bento’s squad and has captained South Korea at the tournament. He has been wearing a protective eye mask (Mirror) but has still featured in all three group games for his country.

Going into the final game of Group H, South Korea were desperately in need of a win to secure their place in the last 16. With Uruguay winning against Ghana, a 1-1 draw against Portugal would have seen Son and his teammates packing their bags and coming home.

But, in injury time, Son picked up the ball in his own half and went on a blistering run. He took on several Portugal defenders before threading an inch-perfect ball through to Hwang Hee-chan, who slotted home to win the game and send South Korea into the knockout stages.

It was a moment which sent the BBC studio into raptures, not least of all Pochettino who was visibly elated to see his former player set up the winning goal. The 50-year-old clapped and cheered, shouting “Oh my goodness, whew!”

Spurs Web Opinion

What a run and what a pass from Sonny. That was such a special moment for the whole South Korea team, and as much as we’d love to see Son get a rest, I’m absolutely delighted that his World Cup journey will continue and he gets to lead his country into the knockout stages.
