It’s different for every circumstance. As was said at the time the reported loan fee and wages were significantly lower than signing his equivalent on a full time deal.
Imo last night was the first time this season that Fati has been disappointing. He has generally been a good signing. Perhaps judgement is clouded for some by too high expectations ?
Yep. I see it as good governance. Many clubs have got into trouble by committing to long contracts they cannot afford in the bad times. Tony is making hay while the sun shines and can do so because of the investment in youth and subsequent return.
