Grant McCann proud of his Doncaster Rovers team for going toe-to-toe with Peterborough United, but he was frustrated with an assistant referee

The former Posh boss saw Rovers beaten 2-1 in a second round FA Cup tie at the Weston Homes Stadium with Ephron Mason-Clark, a player he signed for Posh, scoring the decisive goal.

McCann was also left frustrated by a disallowed goal for Mo Faal midway through the second-half. McCann claims his on-loan West Brom striker was ‘two yards onside.’

Posh were 2-0 ahead at the time, but conceded a goal to Faal 15 minutes to set up a frantic finale.

"We’ve played one of the best teams in League One, if not the best, and more than matched them,” McCann stated. “We’ve gone toe-to-toe with them and I’m so proud of the way we performed.

"Apart from the first 10 minutes when we stood off them and showed them too much respect I felt we were very good. We’ve created chances, but we just needed the rub of the green with a decision. We feel hard done by with the offside call as if it goes the other way we could have earned a replay.

"If Mo’s goal had stood, and he was two yards onside, we would have had 30 minutes to find an equaliser and the way we were playing I fancy we might have got it. The assistant on that side has one job and I expect we will get another apology on Monday morning.

"It was a basketball match at times. They attacked and then we attacked. They are obviously a good side, but we made some great defensive blocks and with a bit more determination and gule up front we might have scored more goals.

“We are disappointed with the goals we conceded. We spoke about not letting players drift inside because if they are allowed to do that they will punish you and that’s what happened. I know Ephron very well as I signed him for Peterborough. He’s a strong, quick, very good player, but I’m more interested in my players and they impressed me.

"We kept going to the end. We hit the post, but we’ve now set the benchmark for the rest of the season. If we play like that in League Two we will soon be climbing the table."

Doncaster are 17th in League Two after suffering a very slow start to the season.
