The day kicked off with a 1-1 draw between Nice and Villarreal, before Eddie Howe's Magpies took to the field to face Fiorentina, who finished eighth in Serie A last season as well as reaching the final of the Europa Conference League.
Goals from Miguel Almirón and Alexander Isak gave United a comfortable 2-0 victory, and put them in a strong position to win the trophy on Sunday.
Then it was the turn of Becky Langley's women to take centre stage, and they ran out 3-0 winners against West Bromwich Albion Women with goals from Bridget Galloway, Becky Ferguson and Cara Milne-Redhead.
