Bayern Munich striker Robert Lewandoski has voiced his frustrations over lack of new signings by the Bundesliga champions.
The Polish striker feels the team lacks depth and might struggle going into the new season if the club does not act and bring in at least three new signings.
Bayern lost Arjen Robben and Franc Ribery at the end of the last season after the duo chose to end their association with the club after a decade each at the Allianz Arena.
In addition, Bayern also lost James Rodriguez, who went back to his parent club, Real Madrid, after two seasons on loan.
"I think we need three new players," he told Bild. "We lost three players in attack with Franck Ribery, Arjen Robben and James, and so far we have not had a [proven] new signing in that area,"
The club has been linked with Manchester City's German winger Leroy Sane, but they are yet to agree on a deal.
Lewandowski, however, feels that even if they succeed in luring Sane, they will need more additions to favorably compete at the highest level.
"We need another attacking winger - even if Sane comes," he added, before suggesting "perhaps a No.6 or a central attacker,"
The new 2019/20 Bundesliga season starts on August 16, with Bayern taking on Hertha Berlin at their Allianz Arena.
