Arsenal's outgoing manager was joined by the likes of Antonio Conte and Jurgen Klopp in wishing the former Man Utd boss a speedy recovery
Arsene Wenger hopes Sir Alex Ferguson's "strength and optimistic character" can help the former Manchester United manager in his recovery from a brain haemorrhage.
Ferguson underwent emergency surgery on Saturday, with his old club confirming the procedure was a success but that the 76-year-old would need a period in intensive care.
The Scot had made an appearance at Old Trafford less than a week before falling ill, presenting Wenger with a special gift in recognition of his years of service prior to United's 2-1 win over Arsenal.
