Toulouse have made an enquiry for Celtic defender Stephen Welsh.
The Ligue 1 side are interested in signing the Scotland U21 international, who started in Celtic's 2-0 home win over Norwich on Saturday.
Sky Sports News understands Celtic do not want to sell the 22-year-old, as he is part of Ange Postecoglou's first-team plans.
In January, the Hoops knocked back a loan, with an option-to-buy, approach from Udinese for the centre-back.
Welsh currently has three years left on his contract.
