Arsenal and Chelsea have both been linked with strengthening their strike options this summer, with Jackson Martinez a name regularly linked.
Neither club have however, taken action to pull the trigger on his €40 million release clause, and the striker has been forced to reconsider his options at Porto.
Over the weekend, Porto announced they had extended his contract by one more year, which will now run up until 2017.
Porto had previously wanted to up his contract to €60 million, but this was a stipulation Martinez and his agent refused, believing it would end his chances of moving on.
As part of the negotiations, he has successfully lowered his release clause to €35 million, which may just tempt interested clubs to make an offer for him.
Yet it is on one condition, as Porto president Pinto da Costa explained: "In the agreement we signed, we decided on three more years of contract and determined that the release fee won’t take effect for this current transfer window or for the January one."
This will give Martinez extra incentive to have a successful season this coming campaign, and ensure he is not distracted by rumours mid-season.
From Chelsea's perspective, given Mourinho's comments he intends to keep Fernando Torres another year, at the end of next season, Martinez would certainly be an upgrade, while if Arsenal fail to win a trophy this season, Arsene Wenger's statement that the Gunners don't need any more strikers will come under more scrutiny.
Martinez scored in Porto's pre-season friendly against Everton yesterday, after coming off the bench at half-time.
