Mourinho was hoping Spurs chairman Daniel Levy would sign a frontman to fill the void left by Harry Kane.
Jose Mourinho says he is "happy" with the transfer business Tottenham have done this January, but insists it "would be better" if they could sign a striker.
The north London side secured the services of Gedson Fernandes on loan from Portuguese club Benfica, made Giovani Lo Celso's deal a permanent one, and also signed winger Steven Bergwijn from PSV Eindhoven.
With Harry Kane injured, Mourinho was hoping Daniel Levy would sign a frontman to fill the void left by the England international.
When quizzed about Tottenham's business in the January transfer window, Mourinho said in a news conference: "I'm happy.
"It would be better with a striker, We would need a striker to have a balanced squad to face the great challenges we have in front of us in three different competitions.
"Steven Bergwijn is the kind of player that is good for now but is also good for our future and is also good for the direction we want to go.
"With the difficulties of the market in January it was really hard to find the striker that is good, not just to resolve the problems of today, but also good for the future of the team."
The former Manchester United boss added: "I am not expecting [more signings]. The market is open so anything can happen but I am not expecting anything to happen. I am happy.
"If it's not possible it is not possible. We are all together for this in the club."
