Bantams boss Stuart McCall feels City can learn a lot from their pre-season friendly defeat to Sunderland this Saturday.
In their first encounter at the Northern Commercials Stadium since the summer break, McCall's men lost out 3-2 to the Black Cats, relegated from the Premier League last season.
After a strong first half showing from the visitors, City found themselves three goals down at the break.
The Bantams had a greater say in proceedings after the restart, however, netting twice to bring themselves within one goal of their opponents by the final whistle.
McCall said: "Sunderland were a big, strong, powerful side - we obviously knew this would be a massive upgrade from the likes of Guiseley, Eccleshill and Echterdingen.
"This game was always going to be about what we could we learn from it - what we did well and what we could do better. But the lads said at half time that they also wanted some pride from the result.
"The last 30-35 minutes of the second half was very encouraging.
"Naturally, we will have to look back at the goals and see what we can do better, but to win the second half 2-0 was definitely a positive.
"There is certainly work still to be done but there were a number of pleasing aspects to take out of the game as well.
"We learned a bit about the lads at half time today (Saturday), we could see their desire to get some pride back into the scoreline at 3-0 down.
"As a manager and a coaching staff, in someways it was good to see Sunderland testing us but it showed us what problems teams might cause us and how we can work against that.
"We have obviously worked on fitness levels and little pockets of play but now we will be starting to get across to the lads, especially the new boys, what we want from them from set-pieces and from general forward and defensive play.
"These next two weeks (before the start of the season) will now give us the opportunity to really get some technical and tactical work into the players.
"That sort of work will be helped over time by playing games, like this, so you can see your errors and plus points dealing with, for example, corners or constructing attacks.
"That is what we enjoy though. As coaches, we enjoy getting out on the training pitch and working and developing the lads."
