Gittens has scored 16 goals in 91 appearances for Dortmund, coming on as a late sub in last season’s Champions League final defeat to Real Madrid.
He has not scored in eight games though as Dortmund have slid down to 11th in the Bundesliga table, winning just one and losing five of their last seven league games.
Former Dortmund and Liverpool striker Karl Heinz-Riedle told SunSport in November that Gittens has the potential to emulate ex-team-mates Jude Bellingham and Jadon Sancho.
TOTTENHAM are eyeing up an audacious summer move for Borussia Dortmund starlet Jamie Gittens.
Dortmund are eight points off the top four but are still in the Champions League, holding a 3-0 lead going into their play-off second leg against Sporting Lisbon.
