Panionios v Newcastle: Craig Bellamy has been told by Newcastle's manager Graeme Souness he will have no future at St James' Park if he continues to attract publicity for reasons that have nothing to do with his performances on the pitch.

Souness spelled that out at a squad meeting he called on Tuesday in the wake of an incident involving Bellamy last weekend, when the Wales striker appeared to swear at his manager on being substituted in the second half at Charlton.

But the pair clashed again at the club's training headquarters before flying out to Greece for tonight's UEFA Cup group stage clash with Panionios.

Souness confronted the Welshman after reviewing his reaction to his decision to substitute him in the 1-1 draw at The Valley, where he had scored the opening goal. However, Bellamy refused to accept the carpeting, sparking an angry exchange which resulted in the two men having to be separated.

The fallout of the past four days could see Bellamy leave Newcastle during January's transfer window.

Souness has taken a firm tone without suggesting his relationship with Bellamy is irreparable, though it is unclear whether Bellamy shares that sentiment. He has not been happy, in any event, at spending time on the wing rather than as a central striker.

What is plain is that Souness will not tolerate behaviour such as Bellamy's on Sunday, which was captured on television.

"What happened yesterday (at the meeting) was a case of me pointing out what I expect from our players," Souness said. "Over the past week we have made headlines for the wrong reasons, and I am determined to stamp out non-football matters.

"Our supporters need to know what is going on at this football club, but it has to be footballing stories that people are writing. The players are aware of how I think of non-footballing stories, taking our eye off the ball. We have a big European game tomorrow and we don't need distractions."

It is not certain whether Bellamy will start against Panionios, but Souness would be making a big statement if he chose not to play the 25-year-old given Patrick Kluivert has not travelled to Greece because of a hamstring injury.

The obvious alternative strike partner for Alan Shearer would be Shola Ameobi, who replaced Bellamy at The Valley but whose fitness needs to be judged after he suffered a reaction to a hip injury. Otherwise Laurent Robert, a left-winger, could be pushed forward into attack.

Souness will want a strong forward line because he acknowledges that attack is Newcastle's best form of defence. "If you look at the players we have, we are geared to going forward and getting after teams and scoring goals," he said. "We're not a team that will set our stall out and try and get a nil-nil. It's been widely acknowledged the strongest part of our team would be our front six and we'll try and play to our strengths."

Souness will want maximum focus against Panionios, who finished sixth in Greece last season but have suffered three defeats in four matches. "We are going into the unknown," he said.
