Blackburn manager Mark Hughes revealed his frustration after his side's goalless draw with Reading on Saturday.
Rovers' best chance fell to Zurab Khizanishvili who found himself onside in the box before striking his attempt wide.
Blackburn then failed to capitalise on the sending off of Reading's Marek Matejovsky with 18 minutes to go.
Hughes is disappointed his side failed to take advantage of the extra man and blames the internationals in midweek for their poor display.
"Frustration is the word, obviously we were in the situation where we had the advantage with the extra man after their sending off," said Hughes.
"I think the international week has taken its toll, certainly on my players. It's been really fragmented and we've not had much preparation for this game.
"There seemed to be a lot of yellow cards and it was never a game that warranted the number of cards shown. That's my view but it's probably echoed by others."
Hughes brought on substitutes Benni McCarthy and Matt Derbyshire in the second half but the strikers could not break the deadlock.
"We were obviously throwing people forward. I'd taken (Andre) Ooijer off to go for the game," he added.
"We had chances ourselves but it just needed the ball to run for us. Given the game that we've just seen, I think 0-0 pretty much summed up the game in fairness.
"It's a long hard season and a lot of the onus has been put on the same players. A number of those were away on international duty and I think today that affected our performance."
