Theo has been lambasted for being sent off for diving on the night and he posted to social media on Wednesday evening: “Football is unpredictable: it offers us great joy, but also painful moments.
“I feel immense frustration today. I apologise to my teammates for having left them down to 10 men and apologise to the fans who always support us.
“But this club is a family and together we will recover. Standing back on our feet all together, starting with me.
“Forza Milan.”
