FC Basel boosted their chances of a place in the Champions League quarter-finals with a shock 1-0 win over Bayern Munich in the last 16 first-leg tie tonight

Having beaten Manchester United 2-1 in Basel last December, the hosts pulled off another stunning victory when midfielder Valentin Stocker found the target in the 86th minute.

The defeat compounded Bayern's flagging confidence ahead of the return leg on March 13 at their Allianz Arena, which also hosts the final on May 19.

While Basel are flying high at the top of the Swiss league, Bayern have won just three of their seven games since Christmas and were held to a goalless draw at bottom side Freiburg last Saturday to leave them third in the Bundesliga.

They have now also gone 240 minutes without a goal.

In Basel, Bayern coach Jupp Heynckes started with Toni Kroos in the central attacking midfielder position, flanked by France wing Franck Ribery and Dutch World Cup finalist Arjen Robben.

It meant no place in the starting line-up for Thomas Mueller, the top scorer at the last World Cup, while Germany striker Mario Gomez was the lone striker.

Ribery tested Basel goalkeeper Yann Sommer twice early on, but the home side almost took the lead in the 15th minute when defender Aleksandar Dragovic forced goalkeeper Manuel Neuer into a reflex save.

Munich were facing one of their future players as Basel's 20-year-old attacking midfielder Xerdan Shaqiri joins their ranks on July 1 and he found space to exploit the guests' defence on several occasions.

Bayern were missing Germany star Bastian Schweinsteiger, who is out with damaged ankle ligaments, but his replacement in Munich's midfield David Alaba tested Sommer with a curling shot on 30 minutes.

Basel captain Marco Streller squandered a good chance on 48 minutes when he headed straight at Neuer.

Bayern controlled possession after the break while the hosts seemed to run out of steam and sat back on some solid defence with the time running out.

Mueller came on for Ribery with 20 minutes left to inject some life into the Germans' attack, but failed to break the hosts' solid defence.

With time almost up, the winner came when Stocker was found at the back post by Cameroon forward Jacques Zoua and the 22-year-old fired home low beyond Neuer to send the home crowd wild.
