Barcelona is reported to have increased its bid for Coutinho to 90 million pounds (US$115 million) this week after two previous offers were rejected by the English Premier League side.
"As there is no other offer from FC Barcelona to date, there is now no transfer of the player to FC Barcelona and this is not now likely".
"We are not worrying about Dembele going to Barcelona".
'We don't know where he is.
Barcelona have been working on a deal to sign the 20-year-old since Neymar's departure to Paris Saint-Germain and the player has also been keen to move to the Nou Camp.
He has been suspended until next week, Dortmund said.
"Ousmane Dembele today missed the BVB-training-session without any excuse".
"As there is no other offer from FC Barcelona until now, the transfer of Dembele to Barcelona isn't likely".
Borussia Dortmund attacker Ousmane Dembele has captured the interest of Spanish rivals Real Madrid and Barcelona this summer.
As Borussia Dortmund participated in media day, everyone among the squad and coaching stuff were enjoying themselves - everyone that is except one Ousmane Dembele.
"We want to have the best possible team".
The former Rennes star, who only joined Dortmund last summer, was absent on Thursday with the club struggling to find his whereabouts.
Dembele's skills on the pitch, including a series of dazzling assists, quickly impressed and earned him "wunderkind" headlines in the German press, though he has been criticised at times for lacking discipline.
