ROME, Sept 22 (Reuters) - Juventus striker Alessandro Del Piero faces a lengthy layoff after injuring a calf muscle during his side's Serie A match against AS Roma at the weekend.

A report in Monday's La Gazzetta dello Sport suggested Del Piero could be out for up to 45 days and miss Champions League games against Real Sociedad and Olympiakos, as well as Italy's final Euro 2004 qualifier against Azerbaijan on October 12.

The Italian international limped off after 14 minutes of the match at Turin's Stadio delle Alpi, which finished 2-2.

'Straightaway I realized I had a muscular problem and asked for the substitution,' Del Piero was quoted as saying on Juventus's official website.

The club said a more precise recovery time would be known after the striker had tests on Tuesday.
