BLACKBURN have hit out at reports casting doubts over Sven Goran Eriksson's appointment as the club's new manager. Stories from home and abroad claimed that Eriksson may opt to stay in Italy, where he is guiding Sampdoria to a title challenge and is also being linked with Lazio who fired Zdenek Zeman on Monday. Tony Parkes, Blackburn's caretaker-manager, said: 'People are delving and seem to want to try to cause a problem. 'Rumours are rumours and there is no point getting worked up about them. 'The club knows the score and Sven has said he will be here as quickly as he can, no later than July and hopefully before.' The Lazio managerial position is uncertain because although Italian goalkeeping legend Dino Zoff has replaced the fired coach Zeman, the Italian coaches' union say Zoff cannot coach the team as well as being the club's president. Head of the coaches' union Azeglio Vicini, who also coached Italy to the 1990 World Cup, said that Zoff's appointment as Lazio coach in place of Zeman contravened his union's rules. Czech coach Zeman was fired on Monday. 'He has to decide. Our rules do not allow a soccer president to be a coach too,' Vicini said. 'Of course I am very glad that Zoff is going to coach Lazio, but he has to resign as president,' Vicini added. Zoff, who won the World Cup as Italy's captain and goalkeeper in 1982, is recognised as a coach and was in charge of the Lazio team before Zeman arrived in 1994. He has said that his return to the bench is only a stopgap measure and a new coach will be in charge next season. The union has protested in the past when clubs have appointed coaches who have not been registered professionally in Italy. At the start of this season six of the seven foreign coaches then active in serie A had the title of 'technical director' to get around the union's ruling regarding foreigners. Ironically, one of those coaches is Sampdoria's Eriksson.
