While I can see the attraction of Rashford, I’d personally prefer we splashed money on 3 or 4 top young players around Europe, and then have them spend 2 years under Emery being whipped into shape before they replace the older players.
Rashford will be expensive wages-wise, but he won't be expensive to purchase, which makes him potentially attractive. To buy a player of similar ability, you'd be looking at spending £70m+ under normal conditions.
I'd love him back, as I think we were a better team with him in it, and he helped us get within a whisker of beating PSG on their way to the Champions League title, but it might be beyond us financially.
Either way, with Unai's reputation never higher, with the club's profile as high as it's been in decades, and with Champions League football next season, I would bet we're a VERY attractive prospect right now for any promising player wanting to prove themselves in the Premier and Champions League.
I'm excited for what the summer has in store for us!
