I’d be delighted if Donnarumma was our keeper next season, but here’s why it won’t happen…
Onana isn’t going anywhere bar Saudi silliness. He’s first choice, got 3 years left, would back himself to play because that’s what top athletes do, even if another keeper arrived and, crucially, is absolutely rubbish so no team he’d want to join would sign him.
As such, if we signed Donnarumma for £40m on £300k+ wages, as a club we’d be spending £20-25m in amortisation on fees and around £500k per week, or £25m a year, in wages on the two of them. Show me a top club that’s spending £50m a year on their goalkeeping department.
Ultimately, we can’t make this kind of signing whilst Onana is first choice. If a cheap option can displace him, then next summer, when he’s only got two years, maybe he’s itching to move. Maybe we could sign Donnarumma on a free then.
