Jenson Button says his one-off return to Formula One at the Monaco Grand Prix is a "dream" scenario and he is confident his recent simulator testing will be enough to prepare him.
After 17 seasons in F1, Button stopped racing at the end of last year and took on an ambassador and reserve driver role at McLaren. The decision appeared to signal the end of his F1 career -- and in normal circumstances it probably would have -- but with Fernando Alonso skipping this year's Monaco Grand Prix to race at the Indy 500, Button is making a return as his former teammate's replacement.
