I thought at the time this was a good deal. Even if I wasn't sure of the value (who really cares about the price we pay if they offer us quality)...
He is versatile, hard-working, and capable of doing so much leg-work both on and off the ball. Once he's settled after this season, those goals will happen more and more, but he has grown so much in his position.
If Lallana and Henderson hadn't improved so vastly on their performances for the club previously, I think the widespread acclaim would be with Wijnaldum.
