The City boss was happy to see the players work hard in the new system at Hartlepool United...
Coventry City manager was pleased with the 1-1 draw at Hartlepool United as the Sky Blues get in the hat for the FA Cup third round draw.
City started the game brilliantly, dominating possession in midfield and got a deserved lead in the 12th minute. Franck Moussa got down the right side and crossed for Carl Baker who produced a superb volley to put City ahead.
The Sky Blues could have doubled their lead with chances for Billy Daniels and Blair Adams before the break but both efforts went wide.
The home side earned a replay 12 minutes from time with a header from Andy Monkhouse but Pressley was happy with his side's energy.
The City boss said: "I thought we started the first 20 minutes really well. We came out of the traps really aggressively and got a wonderful goal to go ahead.
"We were in full control of the game but credit to Hartlepool as they really came back at us. They have already beat three League One teams this season so it was always going to be a difficult afternoon.
"We have played a settled system all year so when you have to change the system, the transition can often be difficult for the players to adjust.
"I think we weren't able to get our high pressing game together in the system we were playing and that pushed us back in the second half."
City came into the game without a senior striker as Leon Clarke is currently injured, Callum Wilson suspended and loan duo Chris Maguire and Chris Dagnall were ineligible.
This meant another Academy product, Courtney Baker-Richardson, made his first team debut against Hartlepool and Pressley believes he will benefit from the experience.
He added: "When you come into a game without a recognised striker and a new system, you have to try and find a way to come out of the game with a result.
"I can't complain at the players because they gave everything today. It wasn't a result we all wanted or our fantastic travelling support, but we are still in the cup.
"There were plus points today, especially the attitude of the players. It was great to see another Academy product come on and get his first appearance for the club.
"Courtney (Baker-Richardson) can take a lot away from the game and it was a good experience. He was actually very unlucky he didn't score. He will definitely benefit from that and that is one of many plus points from the game."
