The Three Lions boss saw his side relinquish control of their clash with Montenegro on Tuesday evening, as they let the lead slip to come away with only a point
Having put eight past lowly San Marino on Friday, the Three Lions looked on course to bag another crucial win after Wayne Rooney's header carved out a sixth-minute lead in Podgorica.
However, the home side improved after the break and snatched a deserved point courtesy of Dejan Damjanovic's late equaliser.
And the 65-year-old admitted standards slipped after the break, especially in midfield, but insisted a draw was a positive result.

“To have won the game we would have had to play in the second half as we did in the first,” he told reporters. “We had a lot of control in midfield initially but we lost that control in the second half.
"Strangely enough, we recovered a bit after that and created some opportunities towards the end where we might have won it. But my overall feeling is one of disappointment because things were looking good for us.
“We didn’t try to see the game out at 1-0. Unfortunately our play in the second half, our ability to keep the ball and dominate central midfield, wasn’t as good in the second half. We had to settle for a draw.
"I don’t think it’s a particularly bad result because Montenegro are a difficult team to beat.”
