Jose Mourinho: 'Summer transfer window important for Tottenham'

Such are their lack of options Mourinho had claimed he would have to prioritise either their game at Burnley on Saturday or Tuesday's Champions League clash at RB Leipzig.

He has since backed down but is not prepared to find himself in a similar position next term.

He said: "We know that we have to build a squad more balanced for next season, because we don't believe that the same situation is going to happen but in football anything is possible and you have to be ready to cope with these unpredictable things.

"So we know everything. We need to give a different shape to the squad to be ready for these unexpected things that happen to us, but we all know that we have to try to win tomorrow and we have to try to win on Tuesday.

"Obviously people are tired of listening to it, but the run of injuries this club had this season, starting with Hugo (Lloris) and ending with Sonny, is something really crazy.

"But again we have to prepare ourselves for something similar to happen again and we have to build a squad that protects against this kind of situation.

"But I believe that any club that loses four fundamental players at the same time, doesn't matter the squad you have, any team would always feel a situation like this."

Such problems have led Spurs to surrender a winning position a number of times in recent weeks, a trait that is not common for a Mourinho team.

"It is not a Jose statistic but a Jose statistic is also based on, when you change players, you change and you improve your team," he said.

"Do you want an example? Arjen Robben on the bench (at Chelsea). And (Damien) Duff and Joe Cole playing. Or vice-versa.

"Minute 70 and one goes out, the other one goes in. You know what the defenders of the opposition do? 'Oh f***'. It's exactly that.

"It's (Cristiano) Ronaldo, (Karim) Benzema and (Angel) Di Maria (at Real Madrid) and then minute 70 you bring (Gonzalo) Higuain, (Jose) Callejon, you know?

"We have the squad for that. Imagine my team playing – Lucas, Kane and Son. And Lucas and Son, minute 70 they are tired. Let's go (Erik) Lamela and (Steven) Bergwijn.

"We have a squad for that. It's not like I'm saying our squad is not good. The squad is good.

"In this moment we are in trouble. It's so simple as that.

"So we are winning and, in the moment we are winning, the moment when you kill the game with fresh players is the moment when our team is going down. So I have an answer for everything.

"But, I repeat, when I see my team next season, pre-season: Bergwijn, Lamela, Kane, Son, (Moussa) Sissoko, Lo Celso, Dele, Lucas..."
