Juan Mata believes his versatility will help him get back into Chelsea's starting line-up.
Mata has been left out of Jose Mourinho's side in recent weeks as the Portuguese tactician has instead opted to start Brazilian starlet Oscar in the no.10 role.
The Spaniard had also been told by Mourinho that he must improve defensively if he is to win back a starting spot.
Mata - who was Chelsea's player of the year last season - had been linked with a move away from Stamford Bridge over the summer as Mourinho was rumoured to be not too keen on the playmaker.
However the 25-year-old is hoping to build on the 90 minutes he played against Swindon Town in the Capital One Cup.
Mata, speaking to The Sun, said: "I've been training hard but it's not the same. You improve your rhythm by playing games.
"I've worked hard and wanted to show everyone that I can play and everything is okay.
"It's easy for me to focus on football and just do what I have to do. The only thing I have in my mind is to keep working, keep training hard, keep improving and keep scoring and making assists. That's what I did.
"I've played in three positions. In the beginning I was playing as a left winger, then on the right and last season as a no.10. I feel comfortable playing in any offensive position.
"It's better if a player can play in lots of positions rather than just one."
Mata will be desperate to force his way into Mourinho's first-team plans - particularly as the former Valencia man was left out of Vicente del Bosque's squad to play Finland and Chile due to his lack of playing time at Chelsea.
