The 'who' has been mentioned countless times here. Whether you like those name or not is your personal choice but there are many fishes in the sea. Wenger is just an ordinary fish we give too much importance to. And yes, there is no 100% guarantee someone else will do better.. there is always risk-reward in every decision and at this point, replacing wenger is well worth the risk. In fact, it shouldve happened many years ago... still better late than never!
