Manchester United legend Roy Keane has blasted Manchester City over their attitude towards Champions League opponents Celtic.
Keane believes Pep Guardiola didn't show enough respect to their opponents.
"Their squad probably isn't as good as maybe Manchester City think or even the manager," Keane told ITV on Wednesday.
"Obviously they knew they were already through but they showed a lot of disrespect to Celtic and Celtic were the slightly better team and could have gone on to win."
