Everton manager David Moyes is determined to try and find out everything he can about prospective new summer signings.
Moyes has prided himself on building a tight-knit unit at Goodison Park and doesn't want to bring in anyone who would upset the applecart.
The Scot told reporters: "For me it is important you get the correct characters."
"Sometimes you have to bring people in who aren't just the exact same because they help enhance the team in the dressing room as well."
"It is not always easy to get all the details about the players' personality. You have to do your homework and find out from the people who are close to them, but you tend to find they say they are great guys and everything is good."
"You have to do a little bit of delving and detective work to try to find out about them."
"But footballers are like anyone else. They want to come and play and be part of a team and part of a good set-up. I think when they get that, they tend to mould together."
