Arsenal defender Calum Chambers insists he'll fight back from his shocking knee injury.

The setback means Chambers' season is over, with the defender to be sidelined for six to nine months.

He posted on Twitter: "Devastated to end 2019 like this! If there's one message I'd like to get across it's that I'm DETERMINED to come back stronger than I've ever been before!

"I would like to say a massive thank you for all the messages and support I've been given over the last couple of days!"
