Celtic want Malick Thiaw and Schalke are yet to fully close the door on a potential summer exit for the young defender.
The Bhoys have signed Cameron Carter-Vickers on a permanent basis but Celtic still want another centre-back.
Curiously, Celtic and Schalke have been closely linked this summer.
Schalke didn’t sign defender Ko Itakura despite a successful loan deal and Celtic showed interest ahead of their move to Borussia Mönchengladbach.
Schalke then targeted Celtic defender Christopher Jullien but that deal fell through and they signed Maya Yoshida instead.
Celtic want Malick Thiaw
The third name is Youngster Thiaw.
Calciomercato reported last week that Celtic had started talks for Thiaw’s signature but Jullien went the other way.
That part of the deal may be off now, but Celtic could still be keen to bring Thiaw to Glasgow this summer.
Thiaw, 20, was in the ranks of Fortuna Dusseldorf, Bayer Leverkusen and Borussia Monchengladbach before joining Schalke in 2015.
A regular at Germany U21s, Thiaw has now made 58 first-team appearances for Schalke and was crucial in promotion last season.
Celtic now appear to have been drawn to Thiaw, who can play for Germany, Finland or Senegal on the international stage.
Thiaw has been linked with Premier League clubs in recent years but Celtic appear to have real hopes of a rather exciting move.
Schalke are opposed financially and aren’t completely ruling out selling the defender this summer.
Schalke’s sports director Rouven Schröder now told the WAZ that Schalke simply cannot buy a player.
While Schroder has hinted that Thiaw fits in well with the Bundesliga and Schalke like him, a move is still possible this summer with Celtic interest.
“There is no such thing as an abrupt no. We have always said that we will deal with incoming offers,” said Schröder. “If the overall theme fits, we also think about it. Malick is here and I think he suits us very well in the Bundesliga. Nevertheless, he is of course in demand because of the U21s and his performances,” he added.
