The Spanish tennis ace triumphed at the clay court tournament last week and felt that it was the perfect response to criticism of his disappointing showings at both Indian Wells and the Miami Open previously.

Alcaraz told reporters: "Perhaps there have been results that have not been enough for some people, even for myself.

"I have reached a point where no defeat is just nothing. But, it is a learning process, and we have to move forward.

"It is easy and free to talk. When someone has an expectation that is not met, it is very easy to talk. That is what I can say."

The four-time Grand Slam winner was not expecting to come out on top in his first clay event of the season in Monte Carlo but says that the victory has provided him with a huge boost.

Alcaraz said: "I can say that in Monte Carlo I gained a lot of confidence.

"I honestly did not expect to win that tournament. Instead, I had just looked to pick up rhythm, play matches, add more hours on clay.

"But winning that trophy has given me a lot of confidence for what is still to come."

Although he triumphed in Monte Carlo, Alcaraz feels there is lots of room to improve his game as he prepares for the defence of his French Open title.

The world number two said: "I do not think that I am at my best level. I think I have played at a better level this year at other points. I have played better matches than those in Monte Carlo.

"It is one thing to win, but it is quite another to really feel that you have played well."
