Jackson Martinez (FC Porto)
Another prolific forward for Arsenal to consider, Jackson Martinez has bagged 39 goals in all competitions for Porto, and over 50 in his last two seasons in total. The 26-year old Colombian attacker is finally reaching his full potential and may have exhausted his options in Porto, but has rejected the chance to move to Liverpool, Tottenham and Napoli. Arsenal should make the effort to sign the forward, as he possesses rare talents in front of goal, with pace, aerial ability and finishing prowess, a rare combination. An instant improvement over their current options, he would be the ideal player to take the Gunners forward and make them a contender.
