There are legit concerns that it would be like playing 10 v 11 when you don't have the ball with Ronaldo in your side. He won't lead your press as a striker, he won't win defensive headers or retrieve the ball when he loses it like Cavani and instead stands outside the area trying to get on the counter.Whoever is against this signing, give your head a wobble. He would improve us greatly and would immediately raise the demands and expectations from those around him in the same way Bruno has.
I also don't get the fuss around him stunting the growth of youngsters, he would help them and they could learn loads from him and give youngsters a taste of what hard work and dedication can achieve.
In two years from now we can have Rashford(25), Greenwood(21), and Amad(21) leading the line for us
His hard work and putting in the hard yards all happen when he wants to get on the end of a ball to score a goal and as he's grown older, he's gotten more economical about where and when he exerts himself.
