Jose Mourinho may well be waking up this morning thinking ‘I wish I had started Marcus Rashford’.
The 18-year-old had to make do with a place on the bench and watched as his Manchester United teammates struggled to cope with the opposition during the opening 45 minutes of the Manchester derby.
But, at half-time with his side trailing 2-1, Mourinho decided he would call upon the teenage sensation as he attempted to turn the game around.
While Rashford couldn’t make any difference to the scoreline in the second half, he showed a fearlessness that Jesse Lingard and Henrikh Mkhitaryan - who were both substituted at the interval - failed to show in the first-half.
And it seems that Rashford impressed one of his teammates during his cameo appearance. Zlatan Ibrahimovic’s arrival seems to have limited Rashford’s playing time but the Swede has made a massive prediction about the wonderkid’s future.
"First of all, he's 18, he's still young. He has a lot of time," Ibrahimovic told MUTV.
"I think the way you have to approach a player like that, where everyone is talking about the talent and what he's able to do and what kind of potential he has, is to remember he still has a lot of time.
"It's not like he needs to take over the world today, the club knows that, the coach knows that and the team knows that.
"We know his quality and what he's able to do. What the world is seeing now, we already know because we see it every day. There is no need to rush to push him and put him in the heat zone and put a lot of pressure on him because that can have the opposite effect.
"Time by time, he will take over everything. It's about having patience."
By 'taking over everything' we assume Ibrahimovic is suggesting he will become United's talisman and one of the world's best strikers.
While some claim that Ibrahimovic may stunt Rashford’s growth by limiting his playing time, others believe the 34-year-old can teach the youngster a thing or two.
And the experienced forward has revealed how he plans on helping Rashford progress.
"I'll help him every day, him and all the others, in any way I can,” he admitted.
“I’m happy it gives an effect but, even if I was not here, they would still do good."
There's probably not a better striker in world football for Rashford to learn from. Not only has he had a magnificent career, he's started life in Manchester impressively, scoring five times in his first five matches.
Rashford is already an incredible talent but if he can learn a thing or two from Ibrahimovic he may 'take over everything.'
