Calling Ronaldo a 'shirt seller'.
It entirely depends on how confident Ole was in Martial actually getting back into form this season. If he was confident, then a DM should have been a higher priority. But if he wasn't, many people would have agreed that a striker would be more important. We would have been left with a badly out of form Martial, an aging Cavani who is increasingly injury-prone and likely to miss parts of the season due to international duties, and Greenwood who hasn't shown any reason to think he's ready to play as a striker yet. Fred/Mctominay/Pogba/Matic/VDB may not be a great selection of midfielders, but it's still better than our striker options would have been. Both Fred and McTominay have started the season significantly out of form which has made it look worse than it actually is.
It's very reminiscent of Fergie buying van Persie instead of a midfielder in his last season.
