First international game i watched as a youngster was: first leg
Red Star v Liverpool 2 - 1, 06 November 1973
Two weeks later:
Liverpool v Red Star 1 - 2
Liverpool with
Clemence
Lawler Lindsay
Thompson Lloyd Hughes
Kevin Keegan McLaughlin Heighway John Toshak Callaghan.
Liverpool all British Red Star all Serbian players.

My Red Star Belgrade was first international team to beat Liverpool in both games.
Year after Kevin Keegan was officially best footballer of Europe.
That was real football, now days money decides which isn't real.
