don't think we can afford Pogba. due to market going crazy since we sold him, he's still worth at least the same amount of money United paid for him which is 105m + he's on really silly wages, close to 10m net, spread over 5 years that's a cost of 35-40m every year.
even if SMS would cost similarly transfer fee wise (but still probably 20-30m less), he'd be happy to earn half of what Pogba would want, which makes him significantly cheaper.
