However, the Portuguese tactician refused to give details about the nature of the Englishman's injury.

While Tottenham will be in action in the UEFA Europa League on Thursday, the Premier League side will have one eye on their weekend fixture which is a highly-anticipated showdown with Arsenal. However, Jose Mourinho has offered a worrisome update ahead of the first North London Derby of this season.

Speaking ahead of the midweek clash with LASK, the Special One admitted that star attacker Harry Kane is nursing an injury and is in danger of missing Sunday's derby. This is definitely a point of worry for the fans given the Englishman's incredible form this campaign, helping Spurs reach top of the table.

The 27-year-old has been at the heart of Tottenham's amazing form, contributing to a whopping 24 goals in 16 appearances across all competitions, scoring 13 and assisting 11. Mourinho refused to offer info as to what his player is suffering from but is hopeful he will recover in time. Regardless, the uncertainty is worrying.

"Harry, Vinicius and Sergio (Reguilon) I believe they have a chance for the weekend," Jose said, as per the Daily Mail.

"I'm not going to tell you the nature of his injury. I think he has a good chance (of playing against Arsenal)," the Portuguese boss added. 

"I don't want to lie, I don't want to hide anything in relation to is he going to play or no? I think he's going to play. My feeling is that he's going to play."

Could Kane miss the upcoming North London Derby or could this be mind games from Jose, something he has done time and time again, given that he refused to reveal the nature of his injury? Then there is the issue of whether his absence would even be a huge blow or not given Arsenal's recent form.

The Gunners recently lost 2-1 to Wolves, their third straight home defeat in the league. This means they now boast only one win from their last six league games and failed to score even once from open play in those games. As a result, the Gunners are 14th in the standings, boasting only 13 points after 10 games and trailing the league leaders by eight points.
