Timber joined Feyenoord in 2022 and has made 105 appearances for the club, scoring 18 goals and providing 13 assists. Last season, however, he struggled with a torn lateral knee ligament, missing the entire second half of the campaign. He still managed 26 matches with six goals and one assist before the injury.
With only a year left on his deal, Feyenoord risk losing him on a free transfer next summer. That could force them to sell now, even if the first offer from Leverkusen was dismissed. Meanwhile, the German club are eager to land the 24-year-old and will continue talks with Feyenoord.
