Roy Keane couldn't believe one statistic about Erik ten Hag's time at Manchester United, sparking a damning assessment of his former club.
The Red Devils' dismal start to the new season has been no secret, with Ten Hag's future in serious jeopardy.
The Old Trafford outfit are on the verge of a group stage exit from the Champions League, following a 3-3 draw with Galatasaray last week.
They returned to Premier League action on Saturday in the hope of turning around their fortunes against Newcastle.

However, their misery was compounded in a 1-0 defeat to Eddie Howe's side, with Anthony Gordon's second-half strike enough to seal all three points at St James' Park.
The result leaves United in seventh place in the Premier League table, some nine points behind league leaders Arsenal.
Meanwhile, Roy Keane has torn into the players and staff at the club, believing their methods of approaching games has reached "insanity".
The former United midfielder was shown a list of Ten Hag's away record against the top nine clubs in the league, which revealed he had taken just one point from 11 matches, conceding a whopping 34 goals in the process.
Keane was left stunned by the graphic, immediately questioning whether it was real.
"That doesn't look real, is that real? It looks ugly," he said on Sky Sports. "The amount of goals they concede, you know. Six at City, seven at Liverpool, four at Brentford.
"It's not good. They're obviously in a tough place and the manager's under pressure. Again, there were players who played last night for Man United and you thought they would have been leaving the club in the summer."
The 52-year-old added: "You're still going back to the same players who have been getting Man United nowhere fast over the last one or two years.
"So, that's a sign of insanity - doing the same thing over and over again and expecting a different result.
"This group is not going to change and if they're not going to work as hard as the opposition, then you're in trouble, and they don't."
