Tottenham boss Mauricio Pochettino is happy employing Heung-min Son at wing-back.

Pochettino is open to using Son as a left wing-back again despite the FA Cup semi-final tactical gamble backfiring against Chelsea.

"Of course [I could use Son again], because I think he was good," he told reporters. "He was unlucky because I think it wasn't a penalty and maybe the feeling is bad but I am so happy with him and if Tottenham play well, it's because of Sonny too.

"It was a little bit unlucky – when you concede the first goal after four minutes, then when you are playing well and you are pushing at 1-1 – for me it wasn't a penalty – and then in second half you dominate completely...

"It was a game where maybe if you play with a different starting XI, maybe the same happens. Always we try to find different ways to play, to be offensive, respect the philosophy and I am happy."
