David de Gea believes Manchester United are still getting used to the "different" approach of interim manager Ralf Rangnick after their inconsistent performances continued against Brighton.
United were lifeless in the first 45 minutes against the Seagulls, but showed more intensity and aggression after the break to record a 2-0 win that takes them back into fourth place in the Premier League.
It was a seventh win in 14 games under the stewardship of interim manager Rangnick, who is trying to bring in a high-pressing game at Old Trafford since replacing Ole Gunnar Solskjaer.
