The Burkina Faso defender has been heavily linked with a move away from Bayer Leverkusen in the ongoing transfer window.
Tapsoba is wanted in the Premier League where Tottenham have him on their radar as they seek to sign two new centre-backs this summer; they have just landed Micky van de Ven, also from the Bundesliga.
He has also emerged onto the radar of Manchester United, who are pushing to bring in a replacement for Harry Maguire who is likely to join West Ham.
It has been claimed that the defender wants guarantees over being a sure starter from his suitors this summer.
Tapsoba does not want to join a club where he will not be in the starting eleven from the onset in the ongoing window.
He wants guarantees that he is being seen as a sure starter before he gives his nod of approval to one of his suitors.
Raphael Varane and Lisandro Martinez are the top-choice centre-backs at Manchester United at the moment.
It is unclear whether Ange Postecoglou would give such a guarantee if Spurs revive their interest in him later in the window.
