Gareth Southgate will be looking for players with 'a hunger' when he delves into the transfer market.
The Middlesbrough boss is attempting to piece together a side capable of bouncing back into the Premier League at the first time of asking.
It is therefore inevitable that he will be looking to bring in new recruits over the summer.
Southgate admits as much and has identified a number of attributes any fresh personnel will have to display in order to catch his eye.
"It's still very early days and we are waiting for the transfer market to move into gear when people start retuning from holiday," the Boro boss told the Evening Gazette.
"But we are focused on what we are looking for. The key element is that we bring in the right kind of character.
"Of course we want to bring in good players, but they have to have a hunger for the challenge of helping to mount a promotion bid.
"If they have experience of the league we are going into then this will obviously help.
"But that doesn't mean we are ruling out signing Premier League players."
With departures from The Riverside also expected over the coming weeks, Southgate knows he must look to replace any experience which heads for the exit.
"One of the things we need is more leadership in the dressing room and on the pitch," he added.
"We also need to get the balance right between experience and energy."
Meanwhile, Middlesbrough have confirmed that 20-year-old winger Graeme Owens has left the club.
The youngster, who spent a period on loan at Blackpool last season, struggled to make the grade on Teesside and has opted to look elsewhere for first-team opportunities.
