Wrexham's 2-1 defeat to Hull City ended a four-game unbeaten run in the Championship and dented hopes of a fourth successive promotion.
But forward Davis Keillor-Dunn, who made just his second appearance since rejoining the Welsh club in February, felt the Red Dragons were beaten by a high-quality opponent.
"They're a really good side. They're up there for a reason," he said.
"You've got to be so well drilled in this league. We chucked everything at them and they kept everything out."
Nathan Broadhead's 76th-minute strike offered hope of a comeback after Hull took a 2-0 lead at Stok Cae Ras, but the Tigers held on to boost their promotion prospects.
Keillor-Dunn said defeat left him "a little bit gutted", but stressed that Wrexham deserve credit for winning three of their past four league games and going toe-to-toe with Club World Cup Champions Chelsea in the FA Cup last Saturday.
"We got one back and tried to get two. The boys have put so much into the last two games," he said.
"Sometimes you just have to give Hull credit, they held on and made it compact at the back."
With an all-Welsh contest against Swansea City coming on Friday, Keillor-Dunn says Wrexham remain in positive mood.
"I came to the club in January and I've got nothing but amazing things to say about this place," he said.
"We're going into every game thinking we can win the game, which is a massive, massive trait to have as a football team.
"We're going to rest up for the rest of the week and go again. The boys are unbelievable professionals in there and they'll be doing the right things to get themselves fit and ready for Friday."
