No he hasn't.
Moyes biggest buy was Fellaini, we made a profit on him, same as we will Lukaku who is Martinez biggest buy. Only difference is that fees have gone up massively due to the over inflated market thanks to billionaires and sky money aplenty.
Moyes bought Coleman and Stones, Roberto's other 2 potential massive windfalls. He even got Naismith on a free, 8m back for him thank you very much Delia Smith! Oviedo at 2.5m, etc etc
Who could we sell that Roberto has bought for a huge profit apart from Lukaku? At the moment nobody, Besic, Del are still to show anything more than promise. Lennon wouldn't go for much more than we bought him for unless he shows consistency over a long period, Mori has potential and has done reasonable well so far, the same could be said of McCarthy. Barry carries no market value at all.
Weird thing is I know you are on the fish but I can't help replying ha
