“WELCOME BACK ENZO” read the tifo beforehand and by the breathless close this was a joyous return for Manchester City’s new manager, Enzo Maresca, as a damaging loss became a memorable win due to Marc Guéhi’s 84th-minute equaliser and Josko Gvardiol’s added-time winner.Until then, Marco Rose had been closing in on leading Bournemouth to a first ever away victory at City. But two lapses in defence and suddenly City were the ruthless proposition they had failed to be before.First, Rayan Cherki floated in a corner from the right and up rose Guéhi to head past Djordje Petrovic, the Cherries No 1 left stranded by a deflection off Adrien Truffert.Maresca, former assistant to Pep Guardiola, sighed hard, then bounced around when the winner was converted.Cherki, a second-half substitute, tapped to Gvardiol and he finished – the video assistant referee ruling this legal after an initial offside flag. So Bournemouth have now lost 13 of their past 14 visits to City – the other result, a draw, in 1989.Zoom out, though, and this remains a disjointed first Premier League outing for Maresca’s side. When Jack Grealish entered on 82 minutes it was for Phil Foden who had been as impotent as Erling Haaland, and City, overall.Maresca, dapper in a baggy suit reminiscent of a 1980s Hollywood movie, had offered a tactical surprise by deploying Guéhi as a holding midfielder, alongside Elliot Anderson, on the £116m signing’s debut.Of interest, too, was Nico O’Reilly, City’s player of the year at left-back, preferred at No 10 to Foden, who lined up on the left. On this showing, this new Maresca blueprint requires work.Rose’s team arrived unbeaten in 18 league games, a fine record achieved under Andoni Iraola, the predecessor who now leads Liverpool, and when Rayan ran in and let fly you saw their potency.Gianluigi Donnarumma saved the effort, an act the keeper’s opposite number did not have to, after O’Reilly, moments previously, whipped the ball in from the left.Haaland, long locks newly shorn to a crew cut, caught between a header and shot, managed only an innocuous chest of the ball, so failed to record goal No 163 on his 200th City appearance.Marc Guéhi heads home Manchester City’s equaliser in the 84th minute.

Rúben Dias and Abdukodir Khusanov had a mix-up, Rayan, profiting, turned the ball to Evanilison whose ball in from the right caught Rico Lewis out of position, and Tavernier poked home.This was excellent for Rose and his men, a head-shaker for Maresca, who went straight to his monitor to dissect how this was allowed. The answer was naivety – and after last weekend’s 3-0 Community Shield drubbing by Arsenal this was a fourth unanswered strike in Maresca’s two most important games – so far.skip past newsletter promotionafter newsletter promotionThe style guide for Maresca’s City could be filed as Pep Guardiola-esque. Quick balls to Haaland and Foden, early, found one that released the No 9 – and the wingers, particularly Antoine Semenyo, to drive in, prime components of the plan.Semenyo claimed a penalty when Adam Smith grappled him – but Jarred Gillett was uninterested, as the referee also was when Anderson, twice, upended a visiting player: the first, on Adam Scott, appeared a yellow card.By the break Rose’s side was the far happier – and dominant. Tavernier spurned two chances to increase their lead and when Evanilson was booked towards the end of the 45 minutes for rough play this showed their ascendancy: Bournemouth were in City’s face.Maresca made zero changes for the second half – of personnel or mode. So Guéhi, not for the first time, proved clunky in an attacking region. Exhibit A: a miss from inches away from an Anderson corner.Further disconnect came when Gvardiol, City’s left-back, fashioned a one-two for a Semenyo on a different wavelength.Maresca’s first change was on 55 minutes – Matheus Nunes for Lewis, who had forced a sharp early save from Petrovic. Then on 61 minutes came Anderson’s enforced removal with what appeared a knee problem, hardly great news for City though he could amble off unaided.This brought Mateo Kovacic as his replacement, as Cherki also took over from O’Reilly – indicating the experiment of him as playmaker was a misfire.Immediately, Cherki fed Semenyo, who caused Petrovic’s opening save of the half and the Frenchman’s quick feet also allowed Haaland to shoot but to no avail.Next, the No 9’s snapshot was gathered by Petrovic and Maresca’s spin on the sideline was one of disappointment – and frustration. But, then, came the end.
