For as long as Jackson Martinez has been a reputable name in Europe Arsenal have been linked with attempts to sign him, that’s generally just how it goes. With speculation over his future hotting up though the Colombia international has taken things to another level by confirming that he now has permission to leave Porto. Arsene Wenger has spoken candidly in the past about how good it would be to have Martinez, who routinely bags over 20 goals a season in Portugal, and with the Gunners in need of an out and out finisher he could be the perfect man to add more momentum to the title charge they’re set to launch next season. Meanwhile new details of Theo Walcott’s demands in his most recent contract talks will have surprised absolutely nobody. It’s said the pacy winger has told Arsene Wenger he wants to be given assurances that he will play as a striker - we know, same old script - but as of yet it’s unclear if Wenger will consent.
