Celtic finished off their Champions League campaign with an encouraging 2-0 win over Villarreal at Parkhead. First-half goals from Shaun Maloney and Aiden McGeady - either side of a red card shown to Guille Franco - gave the Bhoys their first win in Group E.
Boss Gordon Strachan said: "We had a penalty at home against Aalborg and (if we score) we win the game and that's three points.
"We did enough in Aalborg to win the game, everybody in this room whom I met has said we deserved to win.
"We had a smashing performance against Villarreal away and we were six minutes away from beating against Manchester United here although we obviously had our backs to the wall.
"If you look at that then you can count up a few points that went missing.
"But the longer we stay as a group the better it is for everybody.
"If we stay together and don't have to sell anybody, then that will be smashing."
