United continued their preparations towards an opening-day trip to Millwall by losing 2-0 at Mansfield on Tuesday night, but Hockaday feels they are going the right way.
"The quality comes from working with the players we have got," he told the club's official website. "They are improving and they are looking a lot more comfortable on the ball. We are moving the ball around the pitch better, but if we feel that we need to improve with additions to the squad, we will do that."
A second-half brace from Mansfield striker Liam Hearn secured victory for the stags, but Hockaday is adamant Leeds can also take plenty of positives out of this friendly fixture - even if he was left to rue some defensive errors and poor finishing up front.
"I was happy for a lot of the game," said the head coach. "I thought that Mansfield set up to stop us playing, so they showed us respect. It took us a while to get into our stride and, to be honest, I couldn't see them scoring unless we made mistakes. And we did make mistakes.
"I thought that we got stronger as the game went on for the first 60-70 minutes. The thing that disappointed me was that we got into strong positions and we really should have buried them. You want to win every game, so I was disappointed that we got into some great positions and didn't find the back of the net.
"They had two chances and scored two goals, so fair play to them. They were individual errors and we can eradicate those. My concern and my challenge is to make sure that when you dominate a game, we should come away with a victory. We should certainly come away with a minimum of a 0-0.
"We need to stop the individual errors and when we get into good positions we have got to find that pass and put the ball in the back of the net."
