Aitor Karanka says it's business as usual after Boro returned to training and began preparations for the Premier League season on Monday morning.
It was a little under two months ago that a draw against promotion rivals Brighton and Hove Albion sealed Boro's return to the top flight.
And Karanka believes that maintaining the same philosophy that saw Boro reach the top flight will make his side a success in the Premier League.
"After that [Brighton] game everything has changed for us," Karanka said.
"When I was arriving yesterday, I was thinking it seems like a long time since that day. But when we were on the pitch today, I thought that we had never left.
"All of [the players] know how difficult it has been to be in this position.
"Six players that were in the line-up against Brighton were fighting to stay in the Championship with me when I arrived here."
And the Head Coach says that he will give all his squad a chance to earn their place on the teamsheet when Boro kick-off against Stoke City on Saturday August 13.
"I know them, they know me, so for that reason we just keep going," he said.
"Now we have two or three weeks to sign new players, but we are in the Premier League thanks to the players that were here so it's a good few weeks for them to convince me.
"Working together, and going the same way together is the only way. Now, we have to the build the team in the same way to try and bring good players, and keep growing out in the same style."
