Kenny Dalglish has risked infuriating Manchester United ahead of Luis Suarez's appearance at Old Trafford next weekend by again claiming the Liverpool striker should never have been banned for the comments he made to Patrice Evra in October.

Although the Reds were condemned for their initial reaction to the eight-match ban Suarez received for making racist comments to Evra during a Premier League draw at Anfield, it appeared both sides had opted to calm the situation down during the build-up to last month's FA Cup fourth-round tie.

However, the uneasy truce was broken by Dalglish after Suarez had made his re-appearance as a substitute during Monday night's 0-0 draw with Tottenham at Anfield. The Liverpool boss said: "We don't think he should ever have been away but we are delighted to get him back."

He added: "He has not played since December, so it was a wee bit unfair to throw him straight in. He has had half an hour and that will have done him the world of good. It is better than anything we could have done at Melwood."

If Dalglish's comments have raised more than an eyebrow, they followed an equally inflammatory tweet from Wayne Rooney following a challenge by Suarez on Scott Parker that resulted in a yellow card and left the England midfielder doubled up in pain.

"If the referee sees that kick from Suarez and books him for it, it should be red," proclaimed Rooney.

The view was endorsed by former United team-mate Gary Neville in his role as Sky TV pundit. At least Dalglish opted not to get involved in that argument. The Scot said: "He just never saw him."

Then, when informed of what had been said he replied: "Who said that? Why don't you tweet Wayne back and give him your answer.

"I don't have a view on what they have tweeted, especially when I have not seen it. If Neville or Wayne were standing there and asked me the question, I could answer them.

"I don't think you can speak for either Gary or Wayne so unless they want to ask me the question, I will just plead the fifth amendment."
