Manchester United manager Ole Gunnar Solskjaer lauded Luke Shaw, labelling the full-back "absolutely incredible" after his performance in the derby win over Manchester City.
Shaw scored as United upstaged runaway Premier League leaders City 2-0 at the Etihad Stadium on Sunday.
Bruno Fernandes converted a penalty after just 101 seconds before Shaw doubled the lead five minutes into the second half away to City, who had their 21-match winning streak snapped and a run of 28 games unbeaten across all competitions.
Solskjaer hailed Shaw – who joined from Southampton in 2014 – following his impressive display as the England international continues to impress at Old Trafford after his rocky start to life in Manchester.
"Absolutely incredible," Solskjaer said of Shaw. "He was a massive doubt until after the warm-up. He needed to do the warm-up to be cleared to play. So Alex [Telles] was ready but Luke's performance [was] top.
"He's aggressive, he's hard to play one against one. When he goes forward on those on runs he's unstoppable.
"He's just improved so much and he's improving all the time and delighted for him."
United have won three consecutive away games in all competitions against City for the first time since a run of four between November 1993 and November 2000.
The Red Devils are also 22 matches unbeaten away from home in the Premier League, though they remain 11 points adrift of City atop the table.
United star Marcus Rashford limped off with 17 minutes remaining against City and he is set to undergo a scan on his ankle.
Rashford's assist for United's second goal was his 10th across all competitions this season – the first time he has reached double figures for assists in a single season in his club career.
"It's something with his ankle. When he sprinted back about 60-70 yards to save a goal. Just shows the attitude of the boy, and his pace and how he sacrificed himself," said Solskjaer, who became the first manager in United's history to win each of his first three away games against City.
"I think, maybe he went over on his ankle or something, but we need to do a scan. I've not had time to sit down and speak to the doctor yet."
Despite United's success against Pep Guardiola's side, Solskjaer is refusing to look beyond Thursday's Europa League last-16 first leg against Milan.
"All we have to think about is Thursday," he added. "Every game, one game at a time and see where we're at. We want to improve. I want the player to improve. We want to learn from this experience. We want to learn from Wednesday's experience against [Crystal] Palace. We need to improve on so many things to get our consistency better.
"Of course, they're 11 points ahead of us if I'm not wrong, with 10 games to go, so that's a long, long way. So we need to focus on ourselves and just be a better Man United and I feel we're a better Man United now than we were 12, 13, 16 months ago."
