Claudio Ranieri has said that Leicester City must "begin again" and repeat the start of the season.
Leicester lost 5-2 to Arsenal but they remain in sixth place in the Premier League table.
"It was difficult at the beginning and difficult at the end. We touched the post twice and that was our best moment," Ranieri told BBC Sport.
"Arsenal are dangerous on the counter attack. The first half was good and open but at 3-1 it was difficult.
"We shoot at goal at lot of times but Petr Cech is Petr Cech. I hope if we could hold at 2-1 we could force it until late in the game but Alexis Sanchez scored early. The second half was then finished. We must begin again now and repeat this start to the season."
The result was Leicester's first defeat of the season.
