Manchester City captain Vincent Kompany has vowed to support the victims of Monday's terrorist attack and praised the city's resilience.
The defender hailed the emergency services after a suicide bomber killed 22 people and wounded 59 at Manchester Arena after an Ariana Grande concert.
It comes after team-mate Yaya Toure and his agent Dimitri Seluk pledged to donate £100,000 to help the victims.
"We are all shocked and devastated by this attack on the city of Manchester," said Kompany on a video released on the club's Twitter account.

"Nevertheless, the true spirit of Manchester has been able to shine through with the relentless efforts of our amazing emergency services. This is a testimony to the character of this city and the way of life we are prepared to defend.
"No words will ever comfort the families who have lost loved ones but on behalf of Manchester City, myself and my family, I would like to say we stand with you and we will do everything we can to help."

He told BBC Radio 5 live: "I got a call three weeks ago to say I would be working on this game and it was like Christmas Day for me going watching and covering Manchester United on a European night. But from the minute what happened in Manchester, I actually don't want to be at this game tonight, I really don't.
"I actually would prefer to be in Manchester and try to help support in Manchester. I saw there was a shortage of food at the hospital, I rang the hotel that I was part owner in and said, 'Can we get some food down there?'
"It was in Manchester Children's Hospital, the hospital that I was part of the fundraising committee to try and build that hospital. It's part of my life, it's probably the best thing that I've ever done, me and my wife, trying to raise money for that hospital."
