Manchester City and Manchester United will wear their city's worker bee symbol on their shirts for next week's derby in Houston as a mark of respect for those affected by the terrorist attack in May.
The International Champions Cup fixture on July 20 will be the first between the teams since the tragedy which saw 22 people killed and 64 injured after a bomb blast following an Ariana Grande concert in Manchester.
Both clubs donated a combined £1 million to the We Love Manchester Emergency Fund, set up to help victims following the attack.
They will now wear the symbol on the shirts to honour those affected, and the jerseys will then be auctioned off after the match with all money raised going to the fund.
The worker bee is a symbol of Manchester's industrial heritage and has been an emblem since the Victorian era.

Manchester City chief executive Ferran Soriano said: "Manchester continues to show great strength and sense of community since May's devastating attack and the thoughts of everyone at Manchester City remain with those affected.
"The worker bee symbolises everything that makes Manchester such a special city and our players will wear it on their shirts with immense pride, as a demonstration of solidarity with the Manchester community."
Manchester United executive chairman Ed Woodward added: "The city of Manchester has shown great strength and unity since the tragic terror attack in May, showing the country and the world how special this city really is.
"Having the worker bee on our shirts once again shows the community spirit of our city and football club and it is only natural that we continue to help all of those affected, through this fundraising and awareness, with millions of fans across the world watching this game."
