Jota said that he was feeling great. It is a huge step in my career. I joined Celtic to give joy to the fans, to our team and to conquer as many things as possible.
The experience was great. People only know how big Celtic is once they are inside the club and inside the structure.
With the season that we had, I think it was good for everyone, and I just fell in love with the club.
It's a good time to be here and I want to grow.

Bernabei flew from Argentina to Scotland to join Celtic.
The 21-year-old left-back moved to the Scottish champion from Lanus in his homeland's top division on a five-year contract.
I wanted to play in Europe. I have joined a big club like Celtic. I didn't consider it twice.
It's a big competition.
For me, it's just unbelievable, whether it's Paris Saint-Germain or something else. It is a dream come true to come from a small town.
One of the most important tournaments in the world is the European Championship, and we are going to give it all for Celtic. There will be about 60,000 people in the stadium.
I can't wait to play in front of the fans, it will be great. I want to be a champion with Celtic and enjoy my time at the club, first of all.
