Soccer-Roundup-Collina unhappy with Serie A referee

MILAN, Feb 11 (Reuters) - Soccer news in brief from around the world:

* Italian refereeing chief Pierluigi Collina has criticised official Stefano Farina for walking straight off the field and not shaking hands with the players following Inter Milan's controversial 2-0 win at Catania on Sunday.

Esteban Cambiasso was offside when he tapped in Inter's opener in the latest of a series of marginal decisions which have favoured the league leaders recently.

"Referees must shake hands with the players afterwards. It helps dilute tension," Collina told reporters.

* Croatia coach Slaven Bilic will stay on after the Euro 2008 finals, Croatian FA chief Vlatko Markovic was quoted as saying.

"Bilic is likely to be offered a different salary, but he will remain with us after Euro 2008," Markovic told the Jutarnji List daily.

* Barcelona defender Oleguer will miss both legs of his side's Champions League last 16 tie against Celtic after breaking a bone in his left hand during his side's 1-1 draw at Sevilla on Saturday.

The club said on their Web site (www.fcbarcelona.com) that the right back was expected to be out of action for around six weeks.
