Would Man Utd benefit from having Keane? Have your say as ex-captain denied return

Roy Keane could've been sat in the Manchester United dugout had events turned out differently.
The Irishman was lined up to be Ole Gunnar Solskjaer's assistant had the Norwegian got the job on an interim basis in January. Instead Michael Carrick won that battle, excelled initially, got the job permanently and the rest is history.
Keane continues to commentate from the sidelines, be that in the Sky Sports studio or on podcasts alongside Gary Neville. But for years the question has been asked as to whether such an elite leader, one of the club's greats, could bring something to the table in Manchester.
A serial winner during his time at Old Trafford, Keane was perfect for his era. A driver of standards in a way few others were, and plenty feel this current squad need some home truths and someone to set the level.
Conversely, some feel that Keane's methods and take on the game hasn't moved on as much as it should to align with the modern day player. His values can be perceived as old school; he endured an acrimonious exit from the club in 2005 and he's ultimately not been a coach for a number of years - so would he prove an asset or a hindrance?
