Carrick admits the home players were shocked by Basle's attacking approach.
He said: "Thankfully Ashley Young put it away and we might even have nicked a win in the end when Berba had half a chance. But that was probably asking too much."
Young's last-gasp goal - so typical of the Reds - perfectly illustrated Carrick's next point that the summer signing from Aston Villa has fully acclimatised to life at Old Trafford.
"He’s settled in quick and bought into everything about the club and how we approach things," praised Carrick. "He’s got bags of character, he’s kept going tonight and got his reward."
