HEAD coach Steve McClaren has explained why he made a tactical switch at half time during Derby County's defeat by Charlton Athletic, writes Steve Nicholson.
McClaren was disappointed with the manner of Charlton's two first-half goals.
George Tucudean scored Charlton's opener and Yoni Buyens converted a penalty with the final kick of the half after skipper Richard Keogh brought down Tucudean.
Will Hughes was replaced in the holding midfield role by Omar Mascarell, and McClaren said the change was tactical.
"We conceded goals through the middle, and that was disappointing," said McClaren.
"That has been our strength, so it was a tactical switch.
"At Sheffield Wednesday, it [the switch] worked very well. At Charlton, it worked but the result wasn't the same."
Derby lost 3-2, their first defeat of the season.
McClaren said he was close to making changes for the Charlton fixture, but he stuck with the same starting 11 as at Sheffield Wednesday.
"I was close to making changes but decided to stick with what we'd got, go again and give them the opportunity," said McClaren.
"For the first 60 minutes at Sheffield Wednesday, we had to endure, come through it and earn the right to play, which we did.
"The team at the beginning of the game did the work and it was a good point.
"It is a squad game and the substitutes are going to be important, as they were again at Charlton."
The margins in the Championship remain "very fine", said McClaren.
"This Championship is very close, and very inconsistent," he said.
"That is what we are suffering from, inconsistency, while Charlton have found a rhythm very early. That is getting them results.
"I think all the teams in the Championship are improving or have improved."
