Ole Gunnar Solskjær insisted he was still confident of Manchester United having a successful year after a 1-1 draw with Arsenal condemned the 20-times Premier League champions to their worst start to a season for 30 years.

United’s tally of nine points from their opening seven fixtures is the first time since the 1989-90 season they have not reached double figures but Solskjær argued that his team’s performances had merited a better return – and he took a swipe at the media who, he believes, have exaggerated their problems.

“There are many things that give me loads of confidence,” the United manager said. “We can talk about performance but it’s results that matter. You can talk about results, I can talk about six out of seven good performances. West Ham, we know, was below par [losing 2-0] but it wasn’t as bad as you lot made it out to be.”

In a match of low quality, Scott McTominay had given United a first-half lead but Arsenal equalised just before the hour when VAR overturned an offside decision that had initially ruled out Pierre-Emerick Aubameyang’s goal.

“How many times have we been 1-0 up and not got the second goal?” Solskjær said. “This is a steep learning curve for us and we’ll keep working hard and, with more experience, we’ll make the right decisions. It’s another game that we’re 1-0 up – Southampton, Wolverhampton, we need to learn to win these games.”

The draw leaves United in 10th position while Arsenal move up to fourth but the Old Trafford crowd remained supportive of Solskjær and his players – and the manager also received the backing of Roy Keane, his former team-mate.

Keane’s view in his role as a television pundit was that Solskjær should “100%” be given more time. “I think he has been brilliant, a good honest guy,” the former United captain told Sky Sports. “It is hard work at the moment but there are six or seven young players learning their way. We’re all very impatient, we want success yesterday, but you have to give the man time. He is frustrated, under pressure, but dealing with it. He’s a classy guy but no doubt he will be disappointed at not winning enough games.

“They have given him the job, so support him in a couple of transfer windows. Are there more tough days ahead? You bet your life but you need to stick with it. There was a lack of quality from both teams tonight. Their lack of goals, the lack of opportunities they’re creating. Give these boys time. But on tonight’s performance, none of them [neither Manchester United nor Arsenal] will be in the top four.”

Quick Guide Manchester United's worst start in 30 years Show Manchester United have made their worst start to a Premier League season after Monday night's 1-1 draw with Arsenal at Old Trafford. Pressure points: The pressure has built on Ole Gunnar Solskjær as United have taken only nine points from their first seven games – just enough for them to squeak in to the top half of the table. United have won only once since their opening 4-0 victory over Chelsea, with Marcus Rashford's penalty earning them a 1-0 home win against Leicester. Fall from grace: It is just two years since José Mourinho oversaw United's joint-best start to a Premier League season. United claimed 19 points from their first seven games in 2017-18, equalling the starts made by Sir Alex Ferguson's sides in 1999-2000 and 2011-12. United finished runners-up under Mourinho that season, but a whopping 19 points adrift of champions Manchester City. Ole at the wheel: The figures make bleak reading for Solskjær when comparing the Norwegian's record with his predecessors. Mourinho – who would be sacked in December – made a poor start last season, but his 10-point haul from the first seven games was still one more than Solskjær has managed 12 months on. David Moyes also took 10 points from his first seven games in the 2013-14 season, while Louis van Gaal won 11 and 16 points in the respective 2014-15 and 2015-16 campaigns. 30-year low: The last time United made such a poor start to a campaign was under Ferguson in the days of the old First Division. United picked up only seven points from their first seven games of the 1989-90 season, a run that brought successive defeats to Derby, Norwich and Everton and ended with a famous 5-1 thrashing by Manchester City at Maine Road. United ended up 13th that season, but lifted the FA Cup as Ferguson won his first trophy in England. PA Media Photograph: John Peters/Manchester United

Unai Emery, the Arsenal manager, described the game as 50-50 and tried to exonerate Granit Xhaka, the club’s newly-installed captain, for seeming to duck out of the way of McTominay’s shot for the opening goal. Xhaka had played with “big commitment”, according to his manager. Emery added that he had not seen the replays of United’s goal but that he had noted how determined Xhaka was to sprint back into position as the home team launched their counter-attack from an Arsenal corner.

Solskjær, who said that Anthony Martial might not be back from injury until after the next international break, thought his team ought to have been awarded a penalty and he was also unhappy about the unusual circumstances leading to Aubameyang’s goal.

United’s argument was that their players hesitated when they saw the flag being raised. “Ashley [Young] certainly holds his hand up,” Solskjær said. “He looks straight at the linesman and maybe hesitates when he could have got a block in. That probably would have helped David [de Gea] but it is no consolation. It’s a perfectly good goal for them, the linesman probably should have kept the flag down.”

He added: “We didn’t get out of the blocks quickly enough at the start of the second half. It felt like Arsenal were the more proactive until they scored their goal. I felt we could get a goal at the end and we sent men forward. I’ve been in that situation as a player when you come off and think you could have got more out of a game but we’ll learn from this.”
