There was a difference. Last season pep had bigger fish to fry than increasing league points tally and you guys had nothing else to focus but league. When ole came 2nd , we were also in europa semis so fielded a very young side against Leicester at home, as well as took the foot off the pedal against fulham at home. That itself was 5 dropped points. Even the game against Liverpool was rescheduled and squeezed in making it difficult for us to focus.Surely they had the league sewn up even earlier with United 12 points behind them?
Context matters. Again not saying Ole is better than arteta but I agree with couple of posters here that Ole was treated very harshly in compatrison to Arteta. His first real downfall and he was sacked. Arteta got numerous chances to fix his shit. So credit to arsenal board.
