Manchester United’s defensive vulnerabilities returned as AC Milan grabbed an injury-time equaliser in their Europa League last-16 first-leg tie at Old Trafford.

Amad Diallo’s stunning header five minutes into the second half looked like giving United a first-leg lead.

But Milan, who had already been harshly denied a goal when Franck Kessie’s first-half volley was ruled out for handball, replied when Simon Kjaer evaded the attentions of Nemanja Matic at a corner right at the death and steered a near-post header past Dean Henderson’s weak attempt to save.

It was the least a Milan side lacking former United striker Zlatan Ibrahimovic deserved.

It was tough luck on Diallo, who scored in quite brilliant fashion with his first effort on goal in only his third appearance for the Red Devils.

The Ivorian raced on to Bruno Fernandes’ brilliant chipped pass five minutes after replacing Anthony Martial at half-time, then, with his back to goal close to the penalty spot, looped the ball over Gianluigi Donnarumma and into the net.
Amazing Diallo, miserable Maguire
Diallo’s entrance was delayed slightly as he had a band he was wearing on his wrist taped up. It was the only waste of time the 18-year-old was responsible for. It might only be his third United game but he already looks good value for the initial £19m United paid Atalanta for him in January.

Only Mason Greenwood, Marcus Rashford and George Best have scored European goals at a younger age for the club and for a long time, the inspirational effort seemed set to spare Harry Maguire’s blushes for a simply woeful first-half miss.

Maguire timed his far-post run to perfection as he arrived, unmarked, to meet Fernandes’ flick-on from an Alex Telles corner. Amazingly, even though he was barely half a yard out when he connected, Maguire ended up in the net but the ball did not as it flicked off the inside of the post and flew across the six-yard area to safety.
