Manchester City suffered their worst home defeat in Champions League history – with Gianluigi Donnarumma singled out for criticism.The Citizens gloveman watched the ball fly past him a whopping three times in the opening half against Paris Saint-Germain, who ran out 4-2 victors at the Etihad Stadium.Donnarumma had an evening to forget against his former employersAFPCity’s nightmare start marked the first time they’d shipped three goals in the first half at home since 2015, while it was the first time they had trailed by three goals at half-time of a home game since against Manchester United in the FA Cup in January 2012.And legendary talkSPORT broadcaster Adrian Durham, who was at the Etihad Stadium to call the action alongside Andy Gray, believed Donnarumma’s display would give plenty of verbal ammunition to the PSG supporters, who once chanted his name.What did Durham say about Donnarumma?“A word about Donnarumma, he’s let in three,” Durham said at half-time.“Man City have never let in three in the first half of a Champions League tie here ever.“Donnarumma has got to go up the other end in front of the PSG fans in the second half and they’re going to give him, their former keeper, a lot of grief, and he probably deserves it.“That first one, (Desire) Doue’s hit it, it’s not exactly a rocket, he can’t let that pass to me.“He’s ginormous, his reach is huge, he can’t let that go in.”Andy Gray reacts to Gianluigi Donnarumma’s displayGray agreed with Durham’s assessment, especially when it came to Doue’s strike.He remarked: “Listen, if he’s beat far-side with one bent into the top corner like [Jeremy] Doku could do, then you hold your hands up and say, ‘What a finish.’“But that one in that side, near post, you should not be beaten.City hadn’t trailed by three goals by half-time at home since January 2012Getty“And you’re right, Doue hit it OK, but he didn’t hit the back of it crisply, he didn’t fire it in past him and the pace beat him.“It was just bad positioning from the goalkeeper who should have done better.”It was a first half to forget for City, who had former manager Pep Guardiola watching on in the stands.Doue opened proceedings in the 13th minute before Ousmane Dembele doubled the visitors’ advantage just two minutes later with a close-range header.Vitinha completed the first half rout in the 32nd minute with a fine strike from outside the box.Erling Haaland sets Manchester City recordErling Haaland pulled one back for the hosts early in the second half, cementing himself as City’s outright top scorer in the Champions League with 37 goals in 41 games.Guardiola returned to the Etihad Stadium for the first time since he left at the end of last seasonAFPHis smiles before the match were soon gone as PSG smashed City in the first halfBut it proved to be little more than a consolation as summer signing Maghnes Akliouche restored PSG’s three-goal advantage just ten minutes later courtesy of another Donnarumma error.It appeared Donnarumma made a strong save to keep out Akliouche’s long-range strike, only to then palm the ball into his own net.The Italian’s late fumble had Gray scratching his head.“I looked away and was about to say, ‘What a save,'” Gray said.“I can’t believe that. Maybe he should have tipped it over. That’s game over.”Haaland added a second to take his Champions League tally to 38 goals, before Donnarumma somewhat redeemed himself after saving Ferran Torres’ penalty in the closing stages.
