Unai Emery has enjoyed his previous clashes with Brendan Rodgers but is expecting a different challenge when he takes his Arsenal side to face Leicester in the Premier League on Sunday.
The pair have met before, in the group stage of the Champions League in 2017 when Emery was in charge of Paris St Germain and Rodgers at Celtic.
Emery's side ran roughshod over the Scottish champions, winning 5-0 at Parkhead and racking up a 7-1 victory in the French capital.
