Watford midfielder Tom Cleverley has spoken of his time at Manchester United.
Cleverley has recalled thatSergio Aguero goal which meant United lost the league to City in 2012.
He told manutd.com: "I'll never forget in the dressing room after that game. The manager said to us all: 'I told you. That's why I wanted you to be more ruthless and really kill teams, because you can lose leagues on goal difference.'
"And he was right. We'd gone in after beating teams 3-0 or 4-0 that season and he still hadn't been happy with us in the dressing room. That's how much of a winner he was, how ruthless he wanted us to be. If we'd done that, scored more goals, really killed teams, we'd have won the league in 11/12.
"But had we done that, would we have had that real determination to win it the next year and win it as convincingly as we did?"
