The South Korean star has missed our last six matches with a foot injury.
Sonny and Nabil Bentaleb (ankle) are both back in training but Nabil is not yet match fit.
Danny Rose is a doubt after being forced off with a dead leg late in Monday’s win against Villa while Nacer Chadli and Alex Pritchard (both ankle) remain sidelined.
“Sonny is in the squad and in contention,” reported Mauricio Pochettino after training on Wednesday. “We now have to decide if he plays from the beginning or if it’s better to put him on the bench.
“Nabil is training well but he’s not match fit yet. Danny is better, it was a dead leg but it’s not a big issue, he still has a chance, but we have a strong squad and if he isn’t 100% maybe we’ll wait until the next game.”
