Liverpool v Manchester United: Sir Alex Ferguson calls for discipline

Manchester United manager Sir Alex Ferguson has warned his players they must keep their cool at Anfield on Sunday when his side take on Liverpool.

Clashes between the two sides are usually heated affairs with six red cards in the last 11 meetings.

"We've had a lot of players sent off at Anfield. But I don't think the games have ever got out of hand," he said.

"It's going to be meaty, competitive, and we expect that. But I just hope our disciplinary record is good."

Recent red cards

  • January 2011- Steven Gerrard (Old Trafford)
  • October 2009 - Nemanja Vidic and Javier Mascherano (Anfield)
  • March 2009 - Nemanja Vidic (Old Trafford)
  • September 2008 - Nemanja Vidic (Anfield)
  • March 2008 - Javier Mascherano (Old Trafford)

There is also the added spice this time as Luis Suarez and Patrice Evra are likely to go up against each other again following last season's fall-out between the pair.

The Uruguayan failed to shake the French defender's hand before United's 2-1 win over their rivals.

The incident came following Suarez's eight-game ban for racially abusing the United player.

Liverpool and United clashes have been famed for their atmospheres, which can lead to players getting carried away on the pitch.

Nemanja Vidic has been United's biggest culprit with three red cards against Liverpool in the last four years - including two at Anfield.

Ferguson praised the atmosphere at Anfield but has warned his players they must be able to keep their focus on the pitch despite what may be happening in the stands.

"There's a great atmosphere, fantastic, and the kind of atmosphere you want to be involved in.

"It does get emotive, but you just have to handle that," he said.

The United manager will want his side to keep eleven men on the pitch as they go in search for their first win at Anfield since 2007, when they beat Liverpool 1-0.
