The 21-year-old joined Italian giants Roma from Barcelona this summer, in order to get regular first-team action.
“I miss everything that surrounds the club,” Krkic said to Catalunya Radio. “I miss my colleagues, my friends and everyone who cares for Barcelona. I miss a lot of things. I love everything I have here and will always have this feeling of nostalgia. That’s not a bad thing though.
“There’s not a single club out there that can compete with Barcelona. They always aim to win La Liga, the Champions League and everything else.
“The group of players that you see in the Barca dressing room is unique. There are a lot of homegrown players and others who really care for Barcelona a lot as well. The current situation is largely down to them.”
