Champions LeagueInter and AC Milan will play their next Champions League home matches at the San Siro stadium although the crowd capacity will be limited, Uefa announced yesterday.
The venue had been in doubt because of stepped-up safety regulations after a policeman was killed in rioting at a Serie A match in Sicily on February 2nd.
Inter host Valencia on Wednesday next, while AC Milan will play Celtic on March 7th.
In a statement, Uefa said the permitted capacity for the Inter match would be 36,000 spectators, of which 1,800 would be visiting fans.
No capacity has yet been set for Milan's game, although the Uefa statement said 4,500 tickets would be made available for Celtic supporters. When full, the San Siro holds 85,000.
Uefa's decision to allow in Valencia and Celtic fans contrasts with the ban on visiting fans laid down by the Italian Football Federation for domestic games at the stadium.
In Serie A the San Siro is only open to Milan and Inter's season-ticket holders after emergency works last week to install electronic turnstiles brought it closer to complying with safety regulations.
Meanwhile, Celtic chief executive Peter Lawwell claims a policy of "smarter spending" lies behind the Parkhead club's financial rejuvenation.
The Scottish Premier League champions posted a profit before taxation of £17.94 million for the final half of 2006. The interim results compare to a loss of £960,000 to December 31st, 2005.
When the Hoops reached the final of the Uefa Cup in 2003, they still managed to lose almost £8 million.
However, a restructuring of the club by Lawwell, which included introducing incentive-based contracts and accepting lucrative pre-season friendlies abroad, in addition to a successful Champions League campaign this season, has, according to Lawwell, put Celtic on "solid foundations".
He said: "Over a number of years, we made significant losses but now we have a solid foundation.
"The European run this season has played its part but you also have to include others things, such as the pre-season tours and transfers."
"But, during that time, we have still managed to recruit big name players."
