Grant McCann was left to lament his side’s second-half performance as Hull City were beaten 4-1 at Fleetwood.
The Tigers went in at the break level after George Honeyman’s close-range strike cancelled out Harvey Saunders’ solo effort.
But three unanswered second-half goals from Callum Camps, Saunders again and Sam Stubbs meant City’s perfect start to the season came to an abrupt end.
“I thought in the first half it was an even game,” said McCann.
“The first real challenge we had when we conceded first, in terms of how we are going to respond, we responded well. It was a good goal from George.
“The second half, we didn’t see it coming. We simply weren’t good enough.
“We were not at the races. We lost too many individual battles all over the pitch and collectively we weren’t good enough.
“The biggest disappointment was we gave them three of the goals. Two of them were from our throw-ins and they broke and scored. One is a set-play where we’ve lost a man and he’s scored.
“Fleetwood were better than us in the second half but we didn’t make it easy for ourselves.”
