Luis Suarez trains Liverpool Manchester United

Out in the cold! Suspended Suarez trains as team-mates prepare for United firecracker

As tensions build ahead of Liverpool's FA Cup fourth-round tie with Manchester United on Saturday, Luis Suarez braved the elements to train at Melwood.

The Uruguayan will sit out the potentially explosive clash at Anfield as he serves the remainder of his eight-match ban for racially abusing United defender Patrice Evra in October.

He is due to return for Liverpool's crunch Premier League meeting with Tottenham on February 11.

Liverpool's clash with United forms part of an FA Cup race-row replay double as Queens Park Rangers host Chelsea, also at Saturday lunchtime.

The two sets of supporters have taken opposite stances in the wake of Suarez's suspension and that incident stoked the simmering feud which exists between groups of rival fans and, with the case being played out in the full glare of the media – many of whom criticised Liverpool for their defence of Suarez – the issue has rarely been out of the headlines in three months.

Reds boss Kenny Dalglish insisted the focus had to be on football and everyone involved, from the pitch to the stands, had to behave.

'We want to concentrate on going out and playing football and any other sideshow is purely that, it is just a sideshow,' the Scot said.

'Everyone has a responsibility to uphold the names of their respective club and anyone who reports or comments on the game also has the responsibility to make sure they are not trying to incite trouble.

'But it is not only the fans who have to behave themselves; we have a responsibility to behave – but that is the case every time.

'I am sure everyone will be determined to make sure what's done has been done and whatever your grievance is keep it to yourself and let's get on with the game.'

Much has been done to lessen the potential for problems at Anfield.

United boss Sir Alex Ferguson sent a letter to ticket holders appealing for them to work with the stewards in the stadium after previous encounters had led to their allocation being cut because of persistent standing in gangways.

Liverpool managing director Ian Ayre and captain Steven Gerrard have both stressed the focus has to be on football and Merseyside Police earlier this week issued their own guidance, insisting they would be: 'Firm, fair and friendly but take action where necessary against those individuals who may seek to cause problems or misbehave.'
