Warm wishes have flooded in for Sir Alex Ferguson, who is in intensive care after suffering a brain haemorrhage.
The 76-year-old, one of the most successful football managers of all time, had surgery on Saturday.
The operation went “very well”, his former club Manchester United said.
Football fans, including names from the worlds of sport, politics and television, have set allegiances aside to unite in sending their best wishes to one the game’s greats.
In a statement on Saturday, Manchester United said: “Sir Alex Ferguson has undergone surgery today for a brain haemorrhage.
The procedure has gone very well but he needs a period of intensive care to aid his recovery. His family request privacy in this matter.
“Everyone at Manchester United sends our very best wishes.”
Sir Alex’s son Darren, manager of League One side Doncaster, did not attend his side’s final home game of the season against Wigan due to his father’s illness.
