Former Liverpool manager Jurgen Klopp led the way on Tuesday with well-wishes to those injured when a car ploughed into supporters at the club's trophy parade earlier in the week.
More than 50 people were treated for injuries and 11 remained in hospital on Tuesday night in a stable condition.
Speaking on Tuesday night, Klopp said: 'Yesterday just showed the two faces of life.
'The most beautiful face for a long, long time. The parade was incredible, the mood was incredible and from one second to the other, everything changed.
'There are more serious things in the world than football and thoughts and prayers go to the injured people and to the families of course.
