Arsenal had to work hard to find a way past 10-man Newcastle as a second-half own goal from Fabricio Coloccini secured a narrow 1-0 Premier League victory on Saturday.

Arsene Wenger's side maintained their 100 per cent away record but struggled to make the most of their 74-minute numerical advantage following an early red card for Newcastle striker Aleksandar Mitrovic at St James' Park.
