THURSDAY evening proved to be a night to forget for Celtic defender Shane Duffy after the Irishman was partly at fault for all three goals for the Italians as the visitors left Parkhead with all three points.

The on-loan Brighton centre-half failed to clear a delivery into the box for Rade Krunic's opener, was caught out on the counter for Brahim Diaz's second and was too slow to deny Norwegian Jens Petter Hauge for the third goal for Stefano Pioli's men.

It was a disappointing performance from the 28-year-old - and BT Sport pundits Martin Keown and Glen Hoddle pointed the finger at Duffy after the final whistle.

Former Arsenal defender Keown said of the first two goals: “That ball into the box [for the first goal] should have been attacked better, there’s no doubt.

“Here [the second goal] the defending’s really poor. They’ve got to get tighter, Duffy is standing off too much and they get in each other’s way.

“Okay, it’s gone through the player’s legs but Diaz putting that away in far too much space. It’s [Theo] Hernandez running from deep - he’s the full-back.

“The amount of space he had, I just felt they let themselves down defensively. But they changed it at half-time and the second half performance was a whole lot better.”

Hoddle, meanwhile, explained where Duffy went wrong for Milan's late third.

"This is poor defending again one vs one," he said. "I think Duffy’s been out and hasn’t played a lot of football and he looked tired at the end, he just can’t get his hips round quick enough.”

Keown concurred: "He just can’t get around. He gets done for pace and can’t retrieve it.”
