The 21-year-old is delighted to be given a chance to impress in the Premier League, and admits he was keen for a new challenge after failing to establish himself at Barcelona
The Catalan defender arrived at the Britannia Stadium on a free transfer on Tuesday and was a member of the Spain squad who recently triumphed at the European Under-21 Championship.
Muniesa is Hughes' second signing after taking charge at Stoke - following the arrival of Erik Pieters from PSV - and the 21-year-old is delighted to be given a chance to impress in England.
He told the club's official website: "I never imagined I would get the chance to play in the Premier League, but when Stoke called me I decided to come here with my family to speak to them.
"All the people I’ve spoken have shown a lot of confidence in me and I’m really happy that everything has been sorted.
"I’m very happy to be here and to sign for this club. I’m very excited about playing in the Premier League with Stoke City."
Muniesa also explained that, while he played regularly for Barcelona B, he was keen to try something different in a new country and take on a different challenge.
"I’ve always played with Barcelona but I want to try something different and with the support of my family and the people at Stoke and the fans, this will be a good experience for me," he continued.
"My favourite position is central defender. I can also play at left back or in midfield but I feel better when I play centre-back.
"I hope to learn English and do my best for the team and the fans. I want to make them happy."
