Maybe the benefit is purely that Watford (presumably will be paying most if not all of his wages for this season), although one wonders why he was given an extra year at his age if there was a likelihood he might move on loan. No real benefit to us.
We all said we needed at least 1 new striker in - I would say now make that 2.
Unless we wanted a proven striker to play one tier down should we have failed to retain EPL status?
