Bastian Schweinsteiger has urged Manchester United fans to keep the faith as he is confident that Louis van Gaal will bring silverware to Old Trafford.
Supporters have vented their frustration at the style adopted by Van Gaal this season as United have struggled to score of late, managing just four goals in their last six games in all competitions.
Chants of "attack, attack, attack" were heard coming from the terraces once again on Saturday against the Baggies, but Schweinsteiger has called on the club's followers to be patient with the Dutchman, whom he believes will deliver the goods eventually.
The Germany international pointed to Van Gaal's spell at Bayern Munich as evidence of this, saying: "I recognise similarities between Louis van Gaal here and at Bayern Munich.
"In Munich if you remember it took a while before the team understood exactly how we wants to play football. But in the end we won the Bundesliga title and made it to the Champions League final. It is not about October or November, it is about May.
"I remember the fans were unsure about him early on at Bayern but in the end we did the double and so the fans in Munich loved him.
"I am sure Louis will bring success to United. I am convinced about that but we have to do our work and we have to improve. I am convinced it will happen."
