Paul Gascoigne has received messages of support from two Barclays Premier League managers after he was sectioned under the Mental Health Act.
The former England midfielder, one of the most gifted footballers of his generation, was arrested after it was claimed he acted as a 'potential menace' at a luxury hotel.
Gascoigne - who won 57 caps for his country and starred for Newcastle, Tottenham, Lazio and Rangers - was detained after Northumbria Police were called to the Hilton Hotel in Gateshead on Wednesday night.
It followed an incident at the Malmaison Hotel in Newcastle hours earlier, where it was said the star made other guests and staff feel 'threatened'.
The 40-year-old has been treated numerous times for drink and mental health problems. Police said there were no injuries.
Middlesbrough boss Gareth Southgate backed his former Boro and England team-mate to battle back to health.
'It is obviously a very sad situation, but I am sure he will come through it,' said Southgate, part of the England side Gascoigne helped inspire to the semi-finals of Euro 96.
'He has shown a willingness to try to come through it in the past and he is obviously going to have to do that again.'
Gascoigne has endured a series of problems both during and after his playing career, and Southgate voiced the hope that he has the right people around him to help him with his current plight.
'He was the most talented player I played with in the 10 years I was with England,' said the former defender.
'He was loved by everybody because he put everybody else first.
'He would do anything for anybody and, hopefully, people will do the same for him now because he obviously needs that help.'
Wigan manager and fellow north-east native Steve Bruce expressed his sympathy for for the former midfielder.
Bruce, 47, said: 'I know Paul quite well. I have had many a night out with him.
'Like everyone else, I am obviously saddened and shocked.
'We all hope where he is now, he is in the best hands and we hope he can come through this major obstacle.
'He has come through before but he will need the support of everyone around him and let's hope he is okay.'
Gascoigne, who also played for Everton in an eventful career that petered out with ill-fated stints at Burnley, Gansu Tianma and Boston, has a troubled history of emotional instability and erratic behaviour.
He has also been treated on a number of occasions for drink and mental health problems and had several run-ins with the police over the years.
A spokeswoman for the Malmaison Hotel said Gascoigne had been staying there for two weeks when the incident happened.
She said: 'He was a potential menace to other guests who felt threatened by his behaviour so he was picked up by his sister and then he went to the Hilton.'
She added: 'He moved towards the night porter, who felt threatened.'
But she said the night porter was now 'absolutely fine' and will not be pressing charges.
She said Gascoigne had been 'absolutely charming' during his stay at the hotel before the incident.
A spokeswoman for Hilton Hotels said Gascoigne had been there for only a day.
She said there was no trouble before police arrived and he checked in on Wednesday morning.
