Sky Blues' boss is also disappointed with the lack of 'second balls' won as City lost to Bristol City at the Ricoh Arena…Coventry City manager Steven Pressley expressed his disappointment at his side's physicality but praised their second half performance as the Sky Blues lost 3-1 to table topping Bristol City.
Goals from Marlon Pack and Kieran Agard put the Robins two goals up at the break. Substitute Shaun Miller pulled one back for City before fellow sub Scott Wagstaff sealed the win in added time.
The win extended the Reds' lead at the top of League One, and Pressley believed that the visitors had more of a presence in the game, and that allowed them to extend their unbeaten start to this season.
"I think that physical aspects were the difference today," he said. "They had presence, and things like that will cost us in the end. In my mind we lacked physicality, which they had in abundance.
"It's hugely frustrating because you can argue that there wasn't a lot between the two teams, and for a brief period after the goal we were on top. We aren't winning the second balls, and it is bizarre because it is something we focus on so much.
"In training we are working hard at that but we need to transfer that onto the pitch. The first two goals I am disappointed about. The third goal was because we went all out attack, so that doesn't bother me, but the first two do."
Despite the scoreline, the City boss was happy with the performance of 17-year old James Maddison, who came on at half time, as well as Adam Barton who made his first league start of the season.
He continued: "There were encouraging signs. I thought young James played really well when he came on, but we can't rely on a 17-year old.
"I also thought that Adam was a leading light, and fair play to him because he came in and he has impressed me."
City now face off against Oldham Athletic at Boundary Park on Tuesday night, and Pressley has revealed that the squad are more determined than ever to turn recent results around.
He concluded: "What is good to see is that players are self-policing one another. They are making each other accountable for their mistakes and they are making each other better players.
"They like me believe that we have what it takes to turn this around. The first step is to do that on Tuesday night."
