Borussia Dortmund have confirmed that Pierre-Emerick Aubameyang is not for sale amid reported interest from Arsenal and Paris Saint-Germain.
Gabon international Aubameyang, 26, was the top scorer for Dortmund last season with 25 goals in all competitions.
RevierSport suggested that the former Saint-Etienne striker was "not averse" to moving to Arsenal or PSG, especially since he could earn considerably more at either club, although BVB sporting director Michael Zorc told kicker it was "no secret" that his club wanted to keep the forward.
When questioned over Aubameyang's future, BVB CEO Hans-Joachim Watzke told Bild: "Aubameyang stays with us this season. He's not for sale!"
Both kicker and RevierSport say Dortmund could extend Aubameyang's contract, which runs until 2018, in the hope that a pay rise would ward off interest from abroad.
Suddeutsche Zeitung reported earlier this week that Arsenal were willing to pay close to €50 million for Aubameyang, who found the net 16 times in 33 Bundesliga matches last season.
Dortmund are short on attacking options having loaned Ciro Immobile to Sevilla for the season after a disappointing debut campaign.
Zorc said that the player had developed hugely in his second season in Germany after Dortmund paid a reported €13m to sign him from St Etienne in 2013.
