​It's still all very much to play for in the Bundesliga title race, but it seems as though Borussia Dortmund manager Lucian Favre already has one eye on the summer transfer window. 

Dortmund sit behind Bayern on goal difference, having held a commanding lead for much of the season, but with star winger Christian Pulisic already signed on at Chelsea ahead of a €64m move, there is a need for the club to re-vamp their squad in the summer.

One solution, as reported by ​Bild, is Bayer Leverkusen's Julian Brandt, with the German outlet claiming respective €25m moves could be on the cards for the 22-year-old as well as Hertha midfielder Niklas Stark. 

While there is little in the way of expansion on those deals, a report in ​Kicker linking ​Dortmund with 'Gladbach forward Thorgan Hazard affords a little more to work with.

The claim there is that CEO Hans-Joachim Watzke is prepared to sign off on a deal that would surpass the club's current record €30m outlay to secure the 25-year-old as an replacement for Pulisic.

The report also mentions an interest in Celtic's Kieran Tierney, with the left-back having caught the eye of Dortmund scouts as they monitor the progress of Jeremy Toljan in Glasgow. 

It seems, though, as if they have been priced out of a move for the 21-year-old, who has already captained Scotland, for now.
