Manager Roberto Martinez is hoping to attract top-quality recruits to Swansea City this summer.
Martinez is already on the lookout for fresh faces, having seen his side just miss out on the play-off places in League One.
He told the South Wales Evening Post: "We haven't really bid for anyone yet.
"What we have been doing is making sure we've seen possible players in action at least four or five times.
"We have also been working hard to get to know the players, to discover what they are like as people and how professional they are.
"It's important to me that we bring in players with the right attitude, not just good footballers.
"We are working hard on improving every department of the squad and it's vital we do that."
