Conor Sellars is expecting the Bantams to face a “tough” test against Grimsby Town, when entertaining the Mariners on Saturday.
City take on Paul Hurst’s men who enter on the back of eight games unbeaten in Sky Bet League Two.
Given Grimsby’s league position and current run of form, City’s joint manager is wary of the threat they will present.
He said: “Grimsby are picking up points they need, and their unbeaten run is showing everyone in the league they will not just roll over.
“They are hard to beat and we can expect a tough game, which we have said to the players.
“We have seen when going up against teams this season who are in dangerous league positions that they will not give us an easy game, and we cannot afford to get complacent.
“They are fighting as hard as they can to try and get points, and so we have to be wary of what they will bring.”
Despite being held to a draw at Stevenage on Bank Holiday Monday, Sellars was pleased with his side’s results over the Easter weekend.
He is looking for the Bantams to build upon four points in two games - against Boro and Forest Green Rovers - when facing the Cleethorpes outfit.
Sellars added: “We were happy with our Easter games, given the form we were in before.
“We knew it would be a hard game against Stevenage, and knew very much what they were about.
“While it was a little disappointing to have not managed to get all three points, we have to respect the run they are still on and how little goals they concede at home, which makes the fact we scored a good goal against them more impressive.
“We managed to get a few positive results, which gave us a really positive feeling, and will be looking to keep it going.”
