One of 3 players signed from Real Madrid as part of the cash Napoli received for Edinson Cavani, Jose Callejon is perhaps the least well known after Gonzalo Higuain and Raul Albiol.
Signed for €10 million, the pacy winger never really cemented a first team position in Madrid and the move to Napoli was perhaps a welcome one for the Spaniard.
Despite not being a regular under Jose Mourinho, Callejon is still a very tricky customer with frightening pace and a composed finisher.
Used mostly from the bench, he made 76 appearances in his 2 years, with 20 goals a decent return for a bit part player.
Whether he will start, or appear from the bench during the clash with Arsenal on Saturday remains to be seen with fierce competition from Christian Maggio, newly signed Dries Mertens and highly rated Lorenzo Insigne.
But no matter what, the Spaniard will cause real problems for our full backs and they will have their work cut out to keep him quiet.
