Villa managed to beat United 1-0 at Old Trafford after a goal by Gabby Agbonlahor.
United have a chance to bounce back when they host Wolves in midweek.
“We didn’t have the patience in the last third of the field,” said the Serb.
“Aston Villa defended well and were a handful up front. But Chelsea are still not too far from us.
“The gap is only three points. Thankfully the next match comes quickly, which is always important after a defeat.
“It gives you a quick chance to play better and fix what happened in the previous one.”
