Leverkusen's victory over Lazio proved Rudi Voeller right that the club have adequate replacement for Tottenham linked Heung Min Son.
Tottenham may have been given a further boost in their pursuit of Heung Min Son.
Bayer Leverkusen sporting director Rudi Voeller confirmed ahead of the game that negotiations were ongoing, but a deal would be done on their terms, as the South Korean's buyout clause had expired, reported Kicker.
Further comments made ahead of the game by Voeller reported by Focus.de regarding Leverkusen's strength, and ability to replace the 23-year-old, also have an impact.
Voeller said that Leverkusen are equipped to play well without the in-demand star, a bold statement ahead of a do or die Champions League qualifier against Lazio, which they trailed 1-0 from the first leg.
He said: "We are very busy on the offense. While Son is not in the squad, with Mehmedi and Julian Brandt we have great alternatives and also Stefan Kiessling is a great player."
Leverkusen went onto overturn their deficit, winning 3-0 on the night, 3-1 on aggregate.
The result will boost Voeller's confidence that the club can cope well in high pressure situations without Son. The financial reward of qualifying for the Champions League combined with a fee for his services, also gives the Bundesliga side real options heading into the final days of the transfer window.
The one negative is that Leverkusen's qualification for the competition could have caused doubt in Son's mind, with Spurs not involved, but if his club are happy to move him on for the right price, staying is not so attractive, and criticism from his manager Roger Schmidt reported by Sport1 after the game should confirm there is no way back for him.
