Mikel Arteta is hoping his secret dossier on Marcelo Bielsa will get Arsenal back to winning ways at Leeds today and help captain Pierre-Emerick Aubameyang start scoring again.

'I haven't spent any time with him but I know many players (who have played for him) and one of my best friends spent many, many years with him,' Arteta revealed. 'So I know a lot about his methods, who he is as a person, who he is as a manager as well and I admire him.
