I'm not, I'm judging what I saw last season. A player used to time and space to work his magic. He doesn't get that in the prem.
LVG bought him based on what he saw in Holland and the national side when he managed them. Gave him games (played 30 times) and he didn't show anything better Rashford, Martial, Lingard, even Ashley Young at times.
If we'd punted on him from Holland, fair play, we'd have to mould him. But he's shown zero for United, which is why teams interested in him what him on loan, not to buy.
And a proven prem player at the same age? Deulofeu. Because if people feel Depay is better purely based on what he did in Holland, then surely you'll have to look at Del's career in better leagues.
