United finished in the top 10 last season and are now looking for a strong finish this season with a chance to better last season's point tally of 41 in the remaining fixtures.
After helping guide the team to survival for another year, Ritchie told the Evening Chronicle: "I'm not sure we get the credit we deserve.
"I think everyone involved at this club deserves credit.
"I understand the glory days of Keegan and Robson, I understand that everyone keeps looking back.
"I'm not saying that we don't aspire to that, obviously we do.
"We want to be the best players and the best group we can possibly be.
"The manager will always say he wants to strengthen and the players are the same, we want to be competing for our places and we understand that's football.
"You want to finish as high as you possibly can, individually and as a team.
"But you can't take anything for granted in the Premier League."
