Manchester United’s first Premier League loss under Ole Gunnar Solskjaer is the “lowest” moment since he took charge, the interim manager said.
Solskjaer has turned the team’s form around since taking over in December, following the sacking of Jose Mourinho.
The Norwegian has overseen a run of 10 league wins and two draws before suffering defeat at Arsenal on Sunday.
Solskjaer told BBC Sport: “The performance was good but the result was disappointing.”
The former striker has brought a feel-good factor back to United with results that mean they are in the fight for a Champions League spot at the end of the season, as well as reaching the quarter-finals in Europe and the FA Cup.
Such has been the turnaround there have been growing calls from players and supporters to give Solskjaer the job on a permanent basis.
