Celtic have entered the race to sign Noble Mendy this week. Media reports confirm the club are one of at least three teams pursuing the Spanish full-back. Two sides from Germany’s top flight also join the chase. Mendy nearly joined Rangers last season but failed a medical. The transfer collapsed before Celtic made an attempt to sign him this summer. The player stays with his current club, holding a market value estimated at £6.4 million. No check-up has occurred for this potential deal yet. The two clubs must settle a fee before any transfer can proceed. Talks progress slowly as European deals heats up.
