JOTA has told the Celtic supporters they haven’t seen anything yet as he vowed to improve after sealing his return to the club yesterday.

The winger finally put pen to paper on a five-year deal after a successful loan spell at Celtic from Benfica last season, and one of the longest-running transfer sagas of the summer so far.

In explaining the move, Jota said that he felt at home at the club, and that it was the best possible environment for him to develop his talent and reach his full potential as a player, a level he feels is still some way off.

“The club speaks for itself,” Jota said.

“The experience I had last year was amazing to it was an easy choice to make.

“I’m really happy to be standing here. I can’t wait to develop more and for the team to conquer more things.

“There wasn’t a single moment where I thought ‘I wanted to stay’. It was all in one. It was just natural during the weeks and months.

“I had some experiences in the past that were not so good. When I first came on loan, it was just another experience. So I never thought I’d definitely stay here because you cannot guess what’s in the future.

“But throughout the season I just thought ‘Okay, I’m feeling good, I feel at home, this is the right place to develop. So let’s do it.’

“I can promise that I will fight every day to honours the colours of the club. Every day I will fight to be a better person and a better player because I want to achieve a lot of things.

“Imagine for a footballer player to not develop? That’s not the right mentality. You must go to the training pitch every day like ‘Okay – today I will be better than yesterday.’

“This is my mentality. I know I can get better in many aspects of the game. I’m excited to see what I can achieve.”
