Minutes after the transfer window closed, it was revealed that Parck Chu-Young had joined Watford on loan.

It became a bit of a running joke on Twitter than only Arsenal could let a striker leave when they needed to bring one in. In fact, Arsenal started the window with six strikers [Giroud, Bendtner, Sanogo, Park, Akpom and Afobe] and ended it with three. Of course, Park would never have played for Arsenal anyway, but that didn’t make it less joke-worthy.
Park signed for Arsenal in the summer of 2011 in one of the most inexplicable transfers of all time. He has hardly got any playing time at all, often not even making the bench and this is his second loan-spell since arriving at Arsenal after he went to Celta Vigo in Spain last season.
He will join fellow Arsenal man Hector Bellerin at Watford but, unlike Bellerin, is unlikely to return for a career at Arsenal when the loan spell is over.
