The final matchday of the Champions League's group stage games served up a number of upsets, with Real Madrid crashing to their heaviest ever home European defeat -- a 3-0 drubbing at the hands of CSKA Moscow.
Meanwhile Young Boys defeated Juventus 2-1, the same margin by which Viktoria Plzen beat AS Roma. Manchester United woes were also exacerbated as they fell 2-1 to Valencia, who are currently 15th in La Liga with only 18 points from 15 games.
"I played a team with a lot of young players," said Solari, who made seven changes to the starting XI which beat Huesca 1-0 in La Liga at the weekend. "I know it's not a path of roses, and besides, every rose has its thorns," Solari said. "We don't like this result, we wanted to finish with a victory."
In Bern, Guillaume Hoarau scored in either half as Young Boys inflicted defeat on Juventus.
Juventus finish top of Group H on 12 points with United on ten.
"We achieved our objective by winning the group, even on a night where everything seemed to go wrong, maybe we weren't focused enough," said Allegri. "We missed so many opportunities and gifted a penalty, so at the end of the day it was only right that we lost."
United boss Jose Mourinho was his defiant self, saying "nothing surprised" him about a miserable performance.
"I didn't learn anything at all," Jose said. "Nothing surprised me at all."
"I think to qualify in this group is a success, never a failure. To finish second in this group is always a success."
