Lionel Messi scored twice to inspire Barcelona to a 3-0 win over Bayern Munich in the Champions League semi-final first leg at the Nou Camp on Wednesday.

The four-time World Player of the Year put Barcelona firmly in the driving seat to make the final in Berlin next month, scoring a quick-fire double in the 77th and 80th minutes.

Neymar added a third goal deep in stoppage time.

The lopsided defeat meant a painful homecoming for Bayern coach Pep Guardiola, who as the Catalan giants' manager guided them to two European titles.

Juventus saw off titleholders Real Madrid 2-1 in Tuesday's other semi-final first leg in Turin.
