CELTIC have been told they can snap up Red Star Belgrade star Vujadin Savic for £1.5 million after closely monitoring the defender.

The Hoops have been looking at the Balkan market recently and Serbian reports have suggested they have enquired to Red Star about the commanding 27-year-old.

Savic has played for Bordeaux and even had a short, unsuccessful loan spell with Watford three years ago where he didn't play a single game.

But the Hoops are facing competition from Lyon in France and Serie A strugglers Sassuolo, who also want to sign Savic, who is halfway through a two-year deal with his home town club.

Savic admitted this week he may look to go abroad again - he's also played for German clubs Dynamo Dresden, Arminia Bielefeld and Moldovian champions Sheriff Tiraspol.

He said: "Football is a game in which you never know what will happen tomorrow."

"If I stay in Belgrade I will be happy, but if the club wants to sell me this summer, then I will go.

"It won't be up to me."

Red Star want £1.5 million for the ex-Serbian Under 21 stopper, who impressed during this season's Europa League, where he was the mainstay for a defence who only conceded three goals in the six Group Stage matches.

Meanwhile, Celtic goalkeeper Craig Gordon has given manager Brendan Rodgers a boost after revealing that he has returned to training following a knee injury.

The Scotland internationalist, who racked up his 50th cap for his country in the November friendly against The Netherlands, was ruled out for up to 12 weeks after damaging a medial ligament in a collision with former Hoops team-mate Efe Ambrose during the January 27th victory over Hibs.

But the 35-year-old, who was sidelined for two years due to a problem with his other knee prior to joining Celtic in summer 2014, posted an update on social media less than six weeks into his rehabilitation.

Alongside a picture of his football boots and gloves, Gordon said: “It’s been a while, loved having these back on today.”

Although Gordon is still likely to be several weeks away from a return to action, the player's progress will be welcomed by Rodgers and the Hoops supporters.

Stand-in keeper Dorus De Vries came in for criticism during Celtic’s costly 3-0 Europa League defeat to Zenit St Petersburg after he failed to keep out Daler Kuzyaev’s shot from distance, while Scott Bain, brought in from Dundee as back-up in the January transfer window, has yet to feature.
