I would say our biggest problem is off the ball movement around the opponents box, we tend to stand and admire rather than look to move into space. A point well made on a couple of our matches where the commentators said "They pass to feet, not to space".He creates space because he often gets double marked.
He scares defences which leaves us more space for our other very dangerous options.
As for the price well I wouldn't pay 70 or 80 but if they would sell for 50 plus KWP I'd rather do that than 30 or 40 million on a battering ram sort who will more than likely go the way of Jansen as kane when fit is undroppable.
Lo Celso looks the exception to this rule, I'd like Van De Beek instead of Fernandes or Zaha, some of his movement is a joy to watch.
