Arsenal legend Martin Keown has heaped praise on his former club after their 3-0 win over Bodo/Glimt in the Europa League.
Eddie Nketiah, Rob Holding and Fabio Vieira were all on target as the Gunners moved top of group A.
For Keown, the impessive performance was a good marker ahead of a tough game against Liverpool on Sunday.
Speaking to BT Sport, he said: 'Mikel Arteta is right to set the bar high. They're top of the league.
'They've got a a tough game coming up against Liverpool so they need the next lot to prove they need to be at the top.
