He's not "basically praising a 17 year old". You just agreed yourself, he's replaced Lukaku. No top manager would ship their main striker for an unproven 17 year old and then go on to publicly pin pressure on that player to help with the goal burden. Then he went on to not play him when there's only one fit striker in the squad match day thread, and played a center mid out wide on the right. And yes, I'm comparing Greenwood to Pereira because we know the latter is bang average even after his experience and he also went on to operate in areas out of his remit (rotating with Mata on the right position which he had no clue about). The former meanwhile is tipped to make a big impact on the team by his own manager. So yes, you can understand if fans are starting to call Ole out regarding not starting Greenwood. For what it's worth I have no issues with Ole's starting lineup on a standalone basis, but putting it against to what he says about Greenwood it doesn't make a lot of sense.
