Well-respected European football superpowers, Real Madrid and Juventus suffered humbling defeats on Wednesday in their last group games of the UEFA Champions League.

Though Juve and Real Madrid finished top of their groups regardless of Wednesday's losses, they would have been happy to end the group phase on a better note.

Real Madrid suffered their heaviest ever home defeat in Europe on Wednesday when the already-qualified Spaniards were thumped 3-0 at the Santiago Bernabeu by CSKA Moscow in the Champions League.

Feder Chalov put CSKA in front against the group winners and triple Champions League holders with a curling shot in the 37th minute and Georgi Shchennikov doubled the visitors' advantage two minutes before half-time with a scrappy volley on the rebound.

The Russian side's remarkable victory, however, was still not enough to secure them a spot in the Europa League as they were pipped to third place in group G by Viktoria Plzen.

In the other game, two goals from striker Guillaume Hoarau led Young Boys to a shock 2-1 Champions League win over already-qualified Juventus on Wednesday after Ronaldo missed several chances for the Serie A side and Paulo Dybala had a stoppage-time goal disallowed.
