Manchester United boss Jose Mourinho believes his team's form revival is thanks to being stronger defensively.
United have now won their last three games.
Mourinho said: "The team as a team is resolving the defensive problems better than before. I don't want to say it was Bailly or Jones and now Smalling and Lindelof.
"I think the team is more compact more solid, the spirit, the cooperation, the empathy, communication all improve in the team, results bring confidence.
"We are as improving as a team I don't want to say it has the name of Chris (Smalling) or Victor (Lindelof)."
