The Korean sensation suffered a hamstring injury in the 2-1 loss at Arsenal, leaving fans concerned for their season.

The worrying thing about Tottenham's recent trip to Arsenal for the North London Derby was not only the score line, as Spurs lost 2-1 to their bitter rivals to lose ground in the top-four race, but also the fact that star attacker Heung-Min Son walked off the pitch in injury.

The South Korean sensation, who has been in inspired form this season in the Premier League with 13 goals and nine assists, hobbled off in 19th minute after pulling his hamstring. Lamela took his place and since then, fans of the north London giants have been eagerly awaiting an update on his fitness.

Could Harry Kane lose his partner in crime for a substantial time at such a crucial moment in the season or would he be back in no time? Speaking ahead of Thursday's Europa League clash with Dinamo Zagreb, Jose Mourinho offered an update on the deadly Asian.

While the Special One admitted to being unsure when the 28-year-old would return, he confirmed that the attacker is out of their second-leg midweek European tie. Given that Tottenham boast a 2-0 lead, Son might not have played in the trip to Croatia regardless of the injury but fans have a reason for concern.

Given how Spurs have fared when Harry Kane or the Korean ace were out of form, the north London outfit must be wary of a comeback. Fortunately for Mourinho, he could have Lo Celso back in time for the second leg but with how long the Argentine has been sidelined, his chances of making the lineup are low.

"He's looked very confident in these three training sessions," Jose said about the South American midfielder. "I think the team needs him. I think even for other players he will help some, he will scare others and I think we need that."
