Bundesliga champions Borussia Dortmund are keen on Bayer Leverkusen star Andre Schurrle, and may look to swoop before long-term admirers Chelsea.
Roberto Di Matteo's side have been credited with an interest in the Germany international, and were linked with a £20m bid for Schurrle in the summer.
The move never materialised, but talkSPORT reports Chelsea are looking to go back in for the German forward when the transfer window reopens in January, but now face competition from Dortmund.
Bayer Leverkusen previously refused to entertain the notion of selling Schurrle to Chelsea, and the German club, with director of football Rudi Voeller in charge, have made it clear they do not want to sell their best players.
But Chelsea and Dortmund are reportedly not put off by Leverkusen's proclamations, and will look to bid again for the Germany striker at the earliest opportunity.
Dortmund are able to offer Schurrle the chance to move to a Champions League club but stay in Germany, and the Bundesliga champions are thought to be strong rivals to Chelsea as a result.
Dortmund coach Jurgen Klopp is believed to be a huge admirer of Schurrle, and talkSPORT report he will make his move for the 21-year-old in the New Year.
Chelsea have spent heavily to reinvigorate their squad, and Roberto Di Matteo brought in Eden Hazard, Cesar Azpilicueta, Victor Moses and Oscar - all players aged 23 or younger - in the summer transfer window.
But Klopp has a young, vibrant squad of his own, with some of the best German internationals in his first-team, so Chelsea have strong competition for Schurrle.
Marco Reus joined Mario Gotze, Ilkay Gundogan, Sven Bender and Mats Hummels at the Bundesliga club, and the German side have started the Champions League in good form.
