Arsene Wenger London - Arabstoday Harry Redknapp has warned moaning Arsenal fans to be careful what they wish for. Tottenham go into Sunday's north London derby 10 points ahead of their bitter local rivals and for the first time in recent memory recognised as the capital's top club. In contrast, Arsenal are in the midst of a below-par season, virtually resigned to a seventh consecutive trophyless campaign and in danger of losing their Champions League status. The Gunners' disappointing year has left growing sections of supporters questioning whether Arsene Wenger is still the right man to lead the club. But Redknapp insists the under-fire manager is irreplaceable, he said: 'Should Arsenal fans be careful what they wish for? Without a doubt.They have had fantastic times. Fifteen years of Champions League football. It's incredible. 'They can't do any better than what they've got, can they Arsenal? They can't replace Wenger. He has been amazing the job he has done there. 'Having said that, let's hope we can make it a miserable weekend for them. 'You say they've had a rough patch but they are still bang there. By their standards, yes, but you have to look at all the circumstances of what they've been through this year. Victory at the Emirates  will go a long way towards confirming Spurs' position as London's finest. Redknapp said: 'It's the most important thing this year to be honest, finishing top club in London. I really want to be top London club and at least keep that third place if we can - anything above that is a bonus.'
