Roy Keane has offered his condolences to the victims of the Manchester Arena bombing, while the city's two football clubs have combined to pledge £1million to the We Love Manchester Emergency Fund.
The Republic of Ireland assistant manager described the attack as "shocking" and "very scary" after 22 people died and 64 were injured, many of them critically.
Keane, a long-time resident of the area, told RTÉ Sport: "It always seems even worse when it’s on your doorstep. It was shocking news. The people that carry out these acts on innocent people... it’s shocking that we live on a planet like that and very scary.
"You’re always concerned and send your best wishes to the people that suffered.
"I knew where my family were. I knew they were at home. But you always know of people that might be there and thank God my family were not in that area at the time."
The Manchester United great said last night's Europa League win was no consolation as the city mourns 22 of its citizens.
"I personally don’t think it’ll help," Keane said.
"Winning the trophy is not going to bring back the people that have been killed or the people that have been badly injured.
"You just send your best wishes to the people that are suffering. A game of football... it has no bearing on the people’s thoughts or feelings at this moment in time."
As a mark of respect, Manchester United held a minute's silence and wore black armbands during Wednesday night's final victory over Ajax in Stockholm while Manchester City Women will do the same at their Spring Series match against Chelsea Ladies at the Academy Stadium on Thursday evening.
The Manchester clubs have come together for the substantial donation to the fund for the victims of the atrocity.
City chairman Khaldoon Al Mubarak said: "We have all been humbled by the strength and solidarity shown by the people of Manchester in the days since the attack. The hope of both our clubs is that our donation will go some small way to alleviate the daunting challenges faced by those directly affected and that our acting together will serve as a symbol to the world of the unbreakable strength of the spirit of Manchester."
United executive chairman Ed Woodward said: "The barbarism of Monday evening's attack has shocked everyone. Our clubs are right at the heart of our local communities in Manchester and it is right that we present a unified response to this tragedy.
"The money will help, of course but the work of the two clubs and their respective foundation and community scheme can build on the fantastic spirit that Mancunians have shown in the immediate aftermath."
