RB Leipzig chief Oliver Mintzlaff has hailed Chelsea officials who were involved in Timo Werner’s transfer negotiations.

The Germany international will officially join the Stamford Bridge club on July 1, and will not play for Leipzig in their Champions League fixture in August.

Although both parties have agreed not to disclose the transfer fee, Leipzig managing director Mintzlaff has had positive things to say about the negotiation process.

“Negotiations with those responsible at Chelsea were always very respectful, fair and constructive,” Mintzlaff told RB Leipzig’s official website.

“We only wish Timo the best for his challenge in London.”

He said that he is proud of the transfer despite also calling it “a bitter loss”.

“We also consider this transfer a great compliment for our young club,” he added.

“We are proud to have formed a top international striker in just a few years, who now has the quality for an international top club like Chelsea FC.”
