Alan McInally believes Bayern Munich are again contenders for this season's Champions League title.

The Bavarian giants were staring down the barrel of a quarter-final exit after last week's 3-1 defeat to FC Porto in the first leg but recovered in stunning fashion to book their spot in the semi-final.

Pep Guardiola's men produced a brilliant first half, scoring five goals, to eventually 6-1 win at the Allianz Arena and 7-4 on aggregate which has them in with a great chance of clinching their sixth European cup.

"There's no way Guardiola thought it would be 5-0 at half-time," former Celtic, Aston Villa and Bayern striker McInally told skysports.com.

"He might have thought they could get one or two but to dominate the first half like that was stuff of dreams.

"If they weren't contenders after 90 minutes last week, they're certainly contenders now. I've been in the same position, in the semi-finals, and psychologically you know you're almost there. And, after a performance like that, having come back from such a poor away performance, they will have huge belief."
