Everton boss David Moyes knows that despite a successful season, culminating in an FA Cup final appearance, he needs to strengthen his squad if he is to take the Toffees to the next level. "For me it is important you get the correct characters," he said.
"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. Anyone who doesn't you can tell becomes a little bit of an outcast and the good ones shove them aside.
"You just have to weigh it up, get it right and get the right people if you can."
