The Spain international midfielder has linked up with the Gunners on an initial agreement which will run through to the end of the 2018-19 campaign.
Despite penning fresh terms at Camp Nou, the deal which has taken the 25-year-old to Emirates Stadium includes the option for Gunners to push through a permanent transfer in the summer.
According to GOAL.COM, Suarez, has been identified as a player who can compete with Alex Iwobi and Henrikh Mkhitaryan for a place on the flanks during the second half of the season, having previously worked under Emery when the two were at Sevilla in the 2014-15 season.
Raul Sanllehi, Arsenal’s head of football, has been leading negotiations for the Gunners with Barcelona, where he previously worked for nine years.
Suarez’s contract expires in the summer of 2020, although reports have suggested that he has agreed to a one-year extension in order to finalise a loan spell at Emirates Stadium.
An initial €2.5m will be paid by Emery’s side with a summer purchase option expected to be in the region of €20m (£17m/$23m). Arsenal are still in the market for one more loan signing, with PSG youngster Christopher Nkunku and Inter winger Ivan Perisic both being targeted .
