Possibly. In terms of how quickly you turn profit over then yes....there won't be too much better than that.Benfica literally paid €10M for him 6 month ago, now they are getting €120M albeit in installments. Might go down as the greatest bit of football business ever done.
I think they did similar with Felix, maybe he was there a little longer...crazy how they keep doing this & with Felix they didn't pay a penny as he came through their ranks.
