The Glasgow club has entered the race to sign Noble Mendy this week. Sources confirm the club are one of at least three teams pursuing the Spanish full-back. Additional suitors from Germany’s top flight also join the chase. Mendy nearly joined their Glasgow rivals last season but failed a medical. The transfer collapsed before Celtic made a bid to sign him one year later. The player stays with his Spanish side, holding a market value estimated at £6.4 million. No check-up has happened for this potential deal yet. The two clubs must settle a fee before the move can proceed. Talks develop slowly as European deals intensifies.
