After a positive start as Spurs coach, Mourinho has seen results take a turn for the worse in recent weeks, with just one win in five across all competitions.

To make matters worse, Spurs have lost Kane and Moussa Sissoko to serious injuries, while Tanguy NDombele continues to struggle with niggling fitness problems.

The club has been linked with making January moves in the transfer market, with Gedson Fernandes of Benfica and Milan striker Krzysztof Piatek rumoured to be key targets.

Spurs chairman Levy has garnered a reputation as a frugal spender in the transfer market, but Mourinho is optimistic the club can capitalise on the right opportunities should they arise.

Speaking ahead of the Premier League clash with pacesetter Liverpool, Mourinho said: "Even the coaches without injuries, without problems in the squad, the coaches with the best squads — let's say Jurgen [Klopp, Liverpool manager], with the best team, with amazing players and an amazing squad, he was happy to get a new player [Takumi Minamino].

"We [managers] are all the same, but the reality is when I came here two months ago, I knew the situation.

"I didn't know that of course I was going to be without Kane and Moussa for so long, but I knew that the situation was about trying to get the best out of the players we have, and that doesn't change, so I'm focused on the work, the game.

"If the boss [Levy] arrives with a solution that can help us to face these difficult months that we are going to have ahead of us, so be it, that's welcome, but if we don't find the right solution, right opportunity, then we are going to wait for the next summer to make the right decisions for the evolution of the team.

"January is a strange market, it's not an easy market to be in. It's a market of opportunity, a market where an opportunity arises and you have the conditions to do it or you do not do it. We have to be calm and not think about the market — let the market think about us."

Kane is not expected to be back in training again until April, meaning he is likely to miss much of the remainder of the season, and although Piatek has been mentioned as a potential short-term replacement, Mourinho says no one can replace his captain.

"Kane is important, irreplaceable," he said. "There's no player who can replace him, and Moussa was playing so well since I arrived, one of our best performers.

"The bad news is that it's not just a couple of weeks then they're back, it's surgery and a long, long time [out].

"If you allow me, I would like to not speak about Kane and Moussa until they are back, so let's try talking about everything to do with them today.

"It's normal everyone wants to speak about Harry, but I don't want to speak too much because then I'll get depressed and then you are going to say I'm miserable and depressed and in a bad mood, so it's better to talk about things that make me laugh."
