Alejandro Garnacho scores stunning first goal for Man United, assisted by idol Cristiano Ronaldo

Alejandro Garnacho opened his Manchester United account in stunning fashion by putting the Red Devils 1-0 up away at Real Sociedad.

The 18-year-old starlet made a huge impression against Sheriff Tiraspol last week at Old Trafford and was rewarded with a second start of the season by Erik ten Hag.

And he made the most of his opportunity by notching the opener in the final Europa League group stage fixture.

The Argentine starlet was fed in behind by his idol Cristiano Ronaldo and displayed some serious pace to burn before providing a brilliant left-footed finish while off balance.

Sociedad went into the final outing with a perfect record in the group stage and United needed to win by two clear goals to top the group and avoid a play-off against one of the third-placed Champions League teams who are dropping into the competition.

It was a first professional start for Garnacho a week ago, where he came back on to the pitch just so he could walk off with his role model Ronaldo.

Afterwards, he took to social media to post a picture of him with the seven-time Ballon d'Or winner, complete with the caption, "I don't know if it's real or if I'm dreaming."

He followed that up with his first goal this evening and looks to have worked his way into Ten Hag's plans.

Garnacho, who scored twice in United's FA Youth Cup final win over Nottingham Forest last season, is full of speed and skill and loves to entertain down the left flank.

He looks at home in the United first-team and Ten Hag has been impressed with his attitude - though there was a weird moment in training this week when teammate Scott McTominay took off his hat and booted it away.
