Arsenal visit Aston Villa on Saturday looking to put to an end their four-match winless run. Standing in their way will be a familiar face.
When Unai Emery took over at Villa in October the phrase "unfinished business" sprung up all over the place. The Spanish manager was returning to the Premier League for the first time since being sacked by Arsenal in November 2019 after a run of seven games without a win.
Emery took over the Gunners following Arsene Wenger's departure after 22 years in charge. He enjoyed a 22-game unbeaten run in his first season, but it unravelled as they eventually finished fifth in the Premier League and lost the Europa League final to Chelsea.
