Ole is going to be out of the door before he knows it if he's happy to not seriously reinforce the team this summer.
Where is this 3-4 new signings coming from? Why would you even want to handicap yourself if there are reasonable targets available?
There's actually a lot of decent value options available:
Aldeweireld £25mil
Pepe £70mil
Meunier £25mil
Rabiot free
James £20mil
~£150mil adding in Rabiot' agent/signing-on fees
If Lukaku leaves, cheaper replacement = save money.
If Pogba leaves, cheaper replacement = Bruno £80mil will be much less than Pogba fee.
How is that unrealistic?
Everyone will have you believe it's going to be a 3 years rebuild though.
It's not hard, if we mean business this summer.
