The City coach also believes the Sky Blues should have claimed three points as Shaun Miller bagged on his injury return...
Coventry City professional development coach Dave Hockaday believes the Sky Blues 'dominated' the 2-1 defeat to Millwall.
JP Rylah gave Millwall the lead before Shaun Miller equalised for the Sky Blues just before half-time. Kyron Farrell scored the winner for the Lions with five minutes remaining.
City came into the game looking to go three games unbeaten and the City coach believes that should have been the case.
Hockaday said: "We shouldn't have lost that game. It will be a learning curve for the lads as in those type of games, you've got to at least draw and take a point.
"We played a certain system and it wasn't working so we switched it and I thought in the second half, we looked more of a threat.
"We dominated much of the play in the second half and it looked like if either team were going to win it, it was going to be us.
"Hugely frustrating day for the side but the fixtures will keep coming so we move on and learn from the game what we can to progress and ultimately improve."
Al Bangura started for City having signed a short-term deal with the Sky Blues last week and Hockaday believes there is more to come from him.
He added: "I don't think he played as well as he can do. There is definitely more to come from him. He gets a lot of touches and keeps it simple but there were times when they weren't enough options.
"We didn't work hard enough to keep the ball in midfield. He did well in the second half but we couldn't fashion that chance to work the keeper hard enough.
"It shows where we are at the moment. We've got a lot of games coming up in a short space of time so the group will be stretched but we've got to get on with it.
"We had Shaun Miller return from injury today which is a big boost for us but it is difficult for the players at the moment."
