Palace won the FA Cup last season and have since lifted the Community Shield.
Recalling his decision to sign with the Eagles, Pino told the club's website: “I sat down with the coach (Oliver Glasner), and he explained to me the plan, and what I had been doing last year, and he convinced me from the first moment.
“I arrived at a winning club. Last year they had a fantastic season: they won two titles.
“I’ve come here and I’ve joined a winning team, a competitive team, with a lot of hunger, and what we are showing in every game, in every competition. The coach has made it clear that we can do big things. I hope it continues like this.
“We have the two Cups, the Conference League and the Premier League, and we treat each game as a final. In terms of adaptation, with Dani (Muñoz), Jeff (Lerma), Walter (Benítez) and many other teammates, they have made it very easy for me. I am very happy to be here, and to be able to add to the team.”
