Anthony Modeste hit a hat-trick on Saturday to eclipse Robert Lewandowski in the battle to be top-scorer in the Bundesliga this season -- then left his future open.
Pierre-Emerick Aubameyang leads the way for the most German league goals with 23 in as many games after netting Borussia Dortmund's winner in Friday's lacklustre 1-0 victory over second-from-bottom Ingolstadt.
Cologne's Modeste moved up to second in the scoring table with 22 goals in 25 games, leaving Lewandowski -- who netted 30 times to finish as last season's top scorer -- just behind with 21 goals.
Modeste's stellar season continued with some clinical finishing as he needed just under 30 minutes to wrap up his hat-trick in Saturday's 4-2 home win over Hertha Berlin, which left Cologne sixth in the table.
The 28-year-old Frenchman has a contract in Cologne until 2021, but his goals are sure to have attracted Europe's top clubs.
"We played well and I congratulate the whole team -- without them I wouldn't have scored 22 goals," he said.
But when asked about his future in Cologne, Modeste replied: "I'm not thinking about next season, just our next game against Hamburg.
"I'm happy here, we'll see what happens at the end of the season."
Despite his goal haul, Modeste has yet to be called up by France coach Didier Deschamps.
"That doesn't matter. I am happy and have showed today how good I am, that's what matters," he said.
Japan striker Yuya Osako, who gave Cologne an early lead, set up Modeste for his first goal on 35 minutes.
The Frenchman's second followed two minutes later with some superb finishing to make it 3-0 to the hosts.
Hertha's top scorer Vedad Ibisevic pulled a goal back when he converted a penalty, but Modeste finished off a superb Cologne counter on 63 minutes.
Lewandowski, who has scored 33 goals in all competitions for Bayern this season, can add to his league tally against Borussia Moenchengladbach in Sunday's key clash.
