Chester believes that the quality within the Hull squad is a testament to the work done by manager Steve Bruce.
"The changes have been huge during the three-and-a-half years I've been here, but especially in the last two years," he told the Hull Daily Mail. "The quality of players we've been able to bring in has made it a huge turnaround.
"The gaffer has done a great job in bringing in some real quality players and they'll help us keep improving."
Hull will find out who they will face in the third round of Europa League qualifying when the draw is made on Friday.
