Former England and Spurs star Paul Gascoigne says Arsenal and their manager Arsene Wenger supported the 47-year-old.
Gascoigne received £50,000 from the North London club for hospital treatment.
The former midfielder was sectioned under the Mental Health Act in October, but says he is doing better now.
"I rang up (Arsenal) physio Gary Lewin and told him I wasn't feeling great," Gascoigne told the Sun.
"He said to go to hospital as he feared it was pneumonia. Wenger then agreed to arrange £28,000 to pay for treatment. Arsenal also paid £22,000 when I had hip treatment."

Arsenal manager Arsene Wenger claims the club tried to sign Barcelona star Leo Messi when he was a teenager.
The Gunners acquired Cesc Fabregas at the time, but failed to land the Argentine, with rumours circulating that they were unable to buy a flat for Messi's family.
"I think in the end, he was not so keen to move, because it was at a period where Fabregas came, and Fabregas and Messi played together in the same team (at Barcelona Academy). We wanted to take Fabregas, Messi and Pique. It worked only for Fabregas," said Wenger.
"It was not completely down to a flat in the end. It was down to the fact that, in the end, Messi was comfortable at Barcelona."
Arsene Wenger says he won't be asking England manager Roy Hodgson to use Theo Walcott sparingly in upcoming internationals against Slovenia and Scotland.
Walcott is part of a 26-man squad, but has barely featured for Arsenal since returning from cruciate ligament injury that kept him out for ten months.

Arsenal boss Arsene Wenger admits that letting Ashley Cole leave the club is one of the biggest regrets of his career.
In a new book based on Arsenal's unbeatable Premier League season in 2003-4, 'Invincible' by Observer journalist Amy Lawrence, Wenger says that Cole left the club on a 'misunderstanding'.
Commenting on Cole's subsequent departure to Chelsea, Wenger says: "[Cole leaving was] A regret of my career. He left on a misunderstanding between his agent and the club.
"A fantastic fighter as well. The rest of his career has shown how big a player he is. It should have been here."
Wenger also said star striker Thierry Henry was "Usain Bolt with a top football talent".
