The 21-year-old Arsenal prospect has made just one Sky Bet Championship appearance so far this season due to the form of Wes Morgan and Liam Moore in the centre of the Foxes' defence.
But the Spain Under-21 international has vowed to convince boss Nigel Pearson that he is deserving of a spot in the starting XI on a regular basis.
"This is a very important year for me at Leicester. I have to show to myself and Arsenal what I can do and that I can play," Miquel told the Leicester Mercury.
"It has been a little frustrating because I haven't played many games so far, but I have to be realistic. Both the centre-backs, Wes and Liam, have been fantastic so far.
"You want to be in the team, but you have to be conscious of the fact they have been doing great.
"So I just have to keep training as hard as I can to convince the manager I am good enough to be starting.
"Competition is everywhere. That is football and I just have to prove myself.
"I have try to get as much experience and games as I can. Then I must go back to Arsenal and try to get into the team. That will be very tough but that is what I plan to do."
