Erling Haaland score the only goal of Manchester City’s unconvincing home win against newly promoted Coventry City.

Manchester City maintained their winning start to the season to move to the top of the Premier League, but Erling Haaland’s solitary strike against newly promoted Coventry City couldn’t hide the nerves in the Etihad Stadium.

The Enzo Maresca era has started with three consecutive Premier League wins, but it was a far from perfect performance on Saturday as the hosts needed a pair of late saves from Gianluigi Donnarumma to deny Coventry a first top-flight point for 25 years.

Haaland’s header midway through the first half proved decisive for his third goal in as many games this season.

Maresca was able to unleash summer signings Enzo Fernandez and Iliman Ndiaye after their arrivals completed a record outlay by any club of £460 million ($622m) in the transfer market to refresh the City squad after Pep Guardiola’s decade in charge.

Fernandez was supposed to start on the bench after completing his £125 million move from Chelsea to match the Premier League transfer record.

However, an injury to Nico O’Reilly in the warm-up meant the Argentine was thrust into the starting line up.

Ndiaye was also handed his City debut by Maresca alongside Haaland, Antoine Semenyo and Rayan Cherki in a fearsome front four.

Coventry had failed to score in three consecutive defeats to mark their return to the top flight after 25 years.

Yet, Frank Lampard’s men could not have come closer to breaking their duck early on thanks to a gift from Donnarumma.

The giant Italian miscontrolled a backpass and recovered to clear off his own line with inches to spare.

Taiwo Awoniyi and Jack Rudoni also missed big chances to give the visitors the lead before City began to find their stride.

Cherki smashed off the post before Fernandez was involved in the opening goal.

His pass fed Semenyo sprinting down the right and his cross was hung up perfectly for Haaland to head home at the back post.

The Norwegian was denied a second by Carl Rushworth before half-time, but City failed to build on their advantage and were left clinging on for the three points.

Donnarumma was needed to produce two huge saves to deny Loum Tchaouna and Ellis Simms an equaliser and a historic moment for Coventry.

Despite another defeat, there was plenty of encouragement for Lampard that Coventry can compete back in the big time.

Maresca will know City will need to be much improved when they travel to local rivals Manchester United next weekend.

But the blue half of the city move to the top of the table ahead of champions Arsenal’s clash against Chelsea on Sunday.
