The most successful club on the Island of Britannia (Manchester United) before matchday 3 was in pole position to qualify from the Group H of the UEFA Champions League.
Everyone believed they were home and dry after defeating PSG and Red Bull Leipzig, but as fate would have it they have relegated to the fixtures packed lower league of Europe (UEFA Europa League). They won the first two games in the group which many weren’t expecting and then lost to Istanbul Basaksehir the minnow of the group.
This loss caused panic in the way and manner Manchester United Manager (Ole Gunner Solksjaer) approached subsequent games, His poor tactical approaches have cost Manchester United dearly, like using certain tactics with the wrong set of players to execute it and also he is slow to respond to changes when the game is on, only making changes when He has lost the game.
