In an interview to the CNN in Mallorca, the world No. 2 Rafael Nadal opened up on his comeback from a foot injury and his feelings in starting a new tennis season. The Spaniard, who will soon head to Abu Dhabi to compete in the Mubadala World Tennis Championship, said: 'I enjoy the fact that for me, it's a challenge, always, to be back again after a tough period of time because of injuries.

For me, it's a challenge to start a new season. We try things and we work on new things. And at the end of the day, you need to go on court every day with the passion to improve something, and with the motivation to keep on going.' Nadal is satisfied with how 2018 went: 'In a year that you finish as the world No.

2, you win a grand slam, you win Monte Carlo and Barcelona, Rome and Toronto -- so three Masters 1,000s -- you can't say it's not a good year. Obviously, it is a good year.' Nadal also explained what living in Mallorca means to him: 'I am happy when I am on Tour, but I am happy without the Tour.

I am happy being at home, being with the friends, being with the family, playing some golf, being out with the boat. I enjoy life outside of the Tour, but I really know that this kind of life can wait. So I am happy outside of tennis, but of course I am not happy when I am not on the Tour because I am injured.

I am still excited about starting another season. At the age of 32-and-a-half, I never expected when I was 23, 22 to still do what I am. That's something that I appreciate a lot, and I enjoy that fact.' ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
