Hiddink comes out on top against Koeman
Chelsea manager Guus Hiddink managed Southampton counterpart Ronald Koeman when the pair won the European Cup with PSV Eindhoven in 1988.
They later fell out over Hiddnk’s appointment as Netherlands manager in 2014, although both have said there were no hard feelings.
They shared a handshake and a few words before their teams competed in a fascinating match.
Southampton were initially on top but Chelsea showed they had the greater stamina and capitalised on the home side dropping back too much.
The Blues remain unbeaten in manager Guus Hiddink’s 11 league games since he took over from Jose Mourinho.tweet
