David O'Leary says Unai Emery has his work cut out emulating Arsene Wenger at Arsenal

David O'Leary who played a record 722 times for the Arsenal was in no doubt. Unai Emery is in for an exacting season in charge of Arsenal. 'It is really early days,' said O'Leary.' I think he has a hard job. I don't think it is a case of "change of manger, here we go". Arsenal finished sixth last season and sixth was the right place. 'My question now is - the five ahead of them... Manchester City, Manchester United, Liverpool, Chelsea and Tottenham. City and United are what they are. Chelsea have started great. I saw them play against Arsenal in Dublin and I was impressed with them. 'And I can understand the transfer policy at Tottenham. If you have a really good team, it is very hard to say, for instance, go and get another centre-forward. If I am a centre-forward, do I really want to go somewhere where I am behind Harry Kane? 'It wasn't a fluke we finished sixth last season. I think: "Have we got better than the five ahead of us?" I don't think so yet. If we finish higher than sixth, I believe we have done well. 'There will be no-one like Arsene or Alex Ferguson any more. That's gone. Twenty-two years at a club as a manager is an amazing achievement. It will never happen again.
