Former Celtic captain Scott Brown believes Celtic's win over Rangers 'changes the game' following a turbulent week for Martin O'Neill's side. Brown argues that Rangers 'got in their face' and blocked Callum McGregor, making it difficult for others to dictate play. He emphasized the need for players like Benjamin Nygren and Mika Baur to drop under and fulfill their roles.

Brown stressed that who starts best could be crucial, noting Rangers were up for the fight and the first 15 minutes should be a battle. Celtic started very, very slow last week and need to go back to basics with fight and hunger, though they have the talent. Brown warned they cannot have just one of those days against their biggest rivals.
