Berlin: The Bundesliga`s fastest ever goalscorer Karim Bellarabi has signed a new deal keeping him at Bayer Leverkusen until 2020, the club announced on Friday.
The 24-year-old Germany international, linked with a move to Chelsea and Liverpool, had already agreed the new deal in December.
"I`ve improved a lot in my development under coach Roger Schmidt this term," Bellarabi told his club`s official website.
"I`ve become a much better player under his guidance and in his system."
Bellarabi entered the Bundesliga record books last August when scoring the fastest ever German league goal after a mere nine seconds.
The midfielder`s lightning strike against Borussia Dortmund was two seconds quicker than the previous record held by Bayern Munich`s Giovanni Elber.
He has had a stellar season, starting all of Bayer`s 21 Bundesliga matches and finding the back of net on nine occasions.
"I`ve never enjoyed such trust as Roger Schmidt. I will do everything to repay him and Leverkusen," he said.
He made his full international debut for Germany in October in a 2-0 Euro 2016 qualifying defeat away to Poland.
Leverkusen, who are sixth in the table with only four points separating them and a place in the top three, head to fifth-placed Augsburg on Saturday.
