Defender Matt Mills, midfielder Keith Andrews and goalkeeper Andy Lonergan have arrived at the Reebok Stadium since Coyle's side were relegated in May. "We continue to look to add to the squad," Coyle told the club's official website. "Again, availability, finances, a lot of things come in to it, but we certainly want to add to the squad we've got and that's what we're looking to do. "We've got strength in depth with the quality in the squad, but we'll be continuing to monitor the market." Coyle has been impressed with the pre-season form of South Korean Chung-Yong Lee, who spent last season on the sidelines recovering from a broken leg. The Wanderers boss added: "I think Chung-Yong Lee, game by game, continues to get better. He's an outstanding player at any level. Chung-Yong Lee could play anywhere. He's so intelligent on a football level, he's very clever on the ball."
