Koeman well and truly destroyed the long-held myth that winning a manager of the month accolade is a bad omen for your side's next game.
Chelsea boss Mourinho said during the week that he was glad he missed out on the award for that very reason but Koeman jokingly praised the words of the Portuguese.
"Maybe I thank Mourinho for that, he gave my players motivation," he said. "I'm joking of course. I like Mourinho and I look forward to playing Chelsea."
