The duo were teammates at Barcelona, coming through the famous La Masia academy before taking different paths, with Deulofeu leaving on loan and Bellerin opting to join the Gunners.
The latter is now a regular first-team star at the Emirates, just reward for the bravery shown to leave the Catalans to join the club at such a young age.
After enjoying a productive debut season last year, Deulofeu believes Bellerin is now one of the most promising Spanish full-backs and is tipping him to enjoy another highly successful campaign.
“Bellerin is one,” Deulofeu responded when asked which player could step up from the U21 squad. “I love him, he enjoyed a great season last year and the current campaign is heading in the same way.”
The 20-year-old made 28 appearances in all competitions last season, scoring two goals.
Incidentally, Bellerin was only drafted in so soon due to a long-term injury suffered to right-back Mathieu Debuchy, a player Arsenal bought in the summer of 2014 to replace Bacary Sagna.
Despite initially looking a little fragile, Bellerin soon grew into the role and by the end of the season he was widely regarded as the club’s first-choice right-back.
The former Barcelona youngster boasts such speed and directness that he’s a huge asset in the final third, illustrated by his late assist in the 2-0 victory over Bayern Munich last month.
He has everything it takes to become a regular for the Spanish national team, and his pace, with Jordi Alba on the opposite flank, will be a scary proposition for the opposition to handle.
