RANGERS manager Ally McCoist has admitted his former teammate Paul Gascoigne faces the "biggest battle of his career".

The former England football international was back in the public eye this week as it was revealed his struggle with alcoholism had reached tipping point.

Gascoigne, 45, flew to the US and was admitted to a rehabilitation facility in a bid to overcome his demons, with his friends paying the bill for the rehabilitation.

Radio 2 DJ Chris Evans, ex-England teammate Gary Lineker and Britain's Got Talent judge Piers Morgan have pledged to pay his bills, while fans sent messages of support.

McCoist is hopeful, but has admitted Gazza faces a stiff test.

He also welcomed plans for fans to show a display of support for Gascoigne at the next Rangers home game.

He said: "It really does sadden me and it equally worries me.

"He's a smashing lad.Everyone loved him during his time at Rangers and we obviously all wish him all the very best in his battle.

"It's the biggest battle he'll have had in his career and in his life so we wish him well with that because he was a smashing boy."
