The Glasgow club has entered the race to sign Noble Mendy this week. Sources confirm they are one of at least three teams pursuing the Spanish full-back. Additional suitors from the Bundesliga also join the chase. Mendy almost joined Rangers last season but failed a medical. The transfer collapsed before Celtic made an attempt to sign him this summer. The player remains with his Spanish side, holding a market value estimated at £6.4 million. No check-up has happened for this new deal yet. Both teams must agree on a fee before any transfer can proceed. Talks progress slowly as European deals intensifies.
