Leyton Orient boss Russell Slade admitted he was disappointed with the goals his side conceded in their 2-0 defeat at Doncaster Rovers.
The O's were second best as they were comfortably beaten by the League One title contenders.
Slade told the club website: "We were 1-0 down at half time to a set play where we've not marked.
"That was disappointing and the second one we've tried to play an offside trap which certainly didn't come off.
"Yes, they're a good side and yes, they've had opportunities, but the goals we've conceded were slightly disappointing for me to say the least."
