Wayne Rooney is backing Manchester United team-mate Robin van Persie to bounce back from the disappointment of missing a penalty in Tuesday night's 0-0 draw with Real Sociedad in the Champions League.
Van Persie came off the bench in Spain and had the chance to win the game for United, but his second-half spot-kick, controversially awarded after Ashley Young had gone to ground easily
, struck the post.
The Dutchman had replaced Rooney as United's first-choice penalty taker last season after the England international struggled from 12 yards out.
Rooney told PA Sport: "Of course [everyone misses from time to time]. Most forwards in the world miss penalties and that won't affect him, I'm sure."
The goalless draw against Sociedad means United remain unbeaten in Europe this season and are top Group A with eight points from four games, but they are yet to guarantee their place in the knockout stages of the Champions League.
"We're disappointed we didn't get the three points as we had the best chances," Rooney added.
"Overall, though, we can see the positives. We got a clean sheet and we're still top of the group.
"I think coming away from home in the Champions League is always difficult. But we created the better chances and I feel we should have won the game.
"A draw wasn't the worst result for us, though, particularly given the other game finished 0-0 as well. But we're disappointed we didn't get the three points."
