Gordon Strachan has admitted that England were "terrific" in their win over Scotland in the international friendly between the two sides at Celtic Park this evening.
Captain Wayne Rooney scored twice as Roy Hodgson's men clinched a 3-1 win in both sides' final match of the year.
The manager told Sky Sports News: "A couple of factors made that the case tonight, and one was a determined and intense England side. We've got to say well done to England, a team full of Champions League players.
"We're a team a little mentally and physically tired after Ireland. We could have passed the ball better and England tested us in that department, that's for sure., We took on a terrific England side, as good as I've seen them play for a while.
"We needed 10 or 11 players to play well, but if you went into my dressing room now and asked who played well not many would put their hands up. But we got what we wanted, the three points in our group against the Republic of Ireland."
Scotland's next outing will be in March in a Euro 2016 qualifier against Gibraltar.
