Adams told the club website: “In the second half we were much better.
“We continued to show good shape at times and we threatened a number of times, but I am really happy with the way some of our players have played.
“We are going to play another Championship (team) here in Stoke in the League Cup, so this has been a good test for that game.
“Carlisle on Saturday will be a different test as they will play in a style that many teams in League One will this season.”
