I think myself and Oncey were early fans, given how he started his Newcastle career; he looked genuine quality and scored an impressive amount of goals.
But there was certainly a few issues; he didn't seem to be the sort of player who could be trusted - especially away from home - but that's possibly due to how often he was played in different positions, and also the general fragility of Newcastle as they were inexorably relegated. However, there is no denying that his form dropped off a cliff around January, and the lack of guts and fight shown led to him being dropped.
That, allied with his "homer" statistics, suggest some concern about his mental strength. But perhaps part of it was simple fatigue?
He's certainly a quality player when on top form, but whether or not he can deliver that consistency is the question. However, being previously PSV's captain, winning the title and being voted Dutch footballer of the year, would suggest he is worth the risk.
What's equally interesting is that Klopp has certainly identified the need for more very quick, powerful, ball-carrying players who are a goal threat.
It was an obvious flaw in the squad make-up last season, with too many one-paced passers, slowing the game down too much and not offering enough attacking options. He's bought Mane already, and been heavily linked with Sissoko and Dahoud. Wijnaldum is another who gives that additional option as a player; someone who can burst through defences with the ball and run in behind onto passes.
Plus he scored more Premiership goals than any other Liverpool player
