James Chester admits there has been a 'huge turnaround' during his time at Hull City, but considers the changes to be positive.
Chester has been part of the set-up at the KC Stadium since January 2011, with Nigel Pearson snapping him up from Manchester United for £300,000.
The 25-year-old has gone on to make close to 150 appearances for the club, including a goal-scoring outing in the 2014 FA Cup final, and is the fourth-longest serving player on Steve Bruce's books – behind Paul McShane, Mark Oxley and Liam Rosenior.
Chester has seen a number of comings and goings over the last three-and-a-half years, on and off the field, but he feels that Hull have progressed steadily throughout his stay and continue to build towards an even brighter future.
He told the Hull Daily Mail from the club's pre-season training base in Portugal: "The changes have been huge during the three-and-a-half years I've been here, but especially in the last two years.
"The quality of players we've been able to bring in has made it a huge turnaround.
"There's probably only Rosenior, Paul and Oxley who were here before the manager now. That's quite scary really.
"That comes with the progress we've made. You have to strengthen because the gulf in quality is so big.
"The gaffer has done a great job in bringing in some real quality players and they’ll help us keep improving."
Chester is likely to face added competition for his place next season, but he is determined to continue furthering his own game - both domestically and internationally with Wales.
He added: "I feel as though I'm playing my club football at a level where I should be and now I’m really looking forward to giving international football a go.
"I enjoyed it. They've been aware that I could play for Wales for a few years and since Chris Coleman took over he's been ringing me.
"With the injuries I had last season, my debut (against Holland in June) came a bit later than I'd have liked but the time of my career is right."
