The keys to the new 90,000-seat stadium have been handed over by Australian construction firm Multiplex, the FA said in a statement on its website.

But the English game's governing body said it could not confirm that the showcase FA Cup final would take place there on May 19 -- the stadium must first host two "ramp up" events to test the facility.

These will be a community day for local residents to see the stadium on March 17 and the England under 21 team's game against Italy on March 24.

Wembley's re-opening has been beset by repeated delays and financial wrangling which has forced the FA to reschedule England international matches.

Rock band Bon Jovi had been due to open the new stadium last June but they, like veteran rockers the Rolling Stones, Robbie Williams and the reformed Take That, were forced to move venues after building work overran.

Now singer George Michael is due to play the first concert at the stadium, in northwest London, on June 9.
