ARSENAL could come up against Claudio Pizarro in the Europa League after he signed for Cologne.
Former Chelsea striker Pizarro, who turns 39 next week, joins Cologne after leaving rival German side Werder Bremen at the end of last term.
The Bundesliga basement side have snapped up Pizarro after scoring just one goal in their opening six league matches.
Pizarro is the top overseas striker of all time in the German top flight with 191 goals from 430 matches with Bayern Munich and Bremen.

The French forward was sent on loan to Chinese side Tianjin Quanjian in a transfer which could earn Cologne up to £30million.
The retired 85-cap Peru international netted just twice in 31 league and cup games during his single season at Chelsea.
