Mikel Arteta knows exactly what Pierre-Emerick Aubameyang is capable of.
Our captain led us to a record 14th Emirates FA Cup triumph last season, scoring four goals as we breezed past Manchester City and Chelsea to lift the trophy.
Aubameyang also has a proven track record in the Europa League semi-finals with a second-leg hat-trick against Valencia two years ago, and Arteta is confident his No 14 can bounce back from a tough period with another influential performance on Thursday.
"My job, my responsibility, is to protect our players and try to get the maximum out of them," our manager said.
