The first leg of Champions League play-off qualifiers kicked off on Tuesday with a couple of very surprising results.
Scottish champions Celtic were shocked 2-0 by Kazakhstani side Shakhter Karagandy in their first leg and will now need to score at least three goals and concede none when they return to Celtic Park for the return bout next week.
In France, Lyon were reduced to ten men after conceding twice to Real Sociedad in their eventual 2-0 loss to the Spaniards which gives them a very difficult task of progressing to the group stage proper as they prepare for a tough trip to San Sebastian next Wednesday.
Dutch giants PSV Eindhoven were able to score in the second half through Tim Matavz to force a 1-1 draw with seven-time winners AC Milan who were served by a 15th minute opener from Stephan El Shaarawy at the Philips Stadion ahead of next week's trip to the San Siro.
Russian outfit Zenit St Petersburg put one foot in the group stage with a 4-1 win in Portugal over Pacos de Ferreira on the back of a Roman Shirokov hat-trick whilst Czech champs Viktoria Plzen beat Slovenia's 3-1 at home.
