Brighton boss Gus Poyet says he wants to build a team around new signing Craig Mackail-Smith after snaring the highly sought-after Peterborough striker. The Seagulls have seen off competition from a host of other clubs to secure Mackail-Smith signature on a four-year contract. The fee is reported to be Â£2.5million, but could rise to Â£3.2million with add-ons. The Scotland international scored 35 goals for Posh last season as they secured promotion to the Championship, making him hot property.. Championship rivals Leicester and West Ham both had Â£3 million bids accepted, while QPR were also reported to be interested. Poyet told the club's official website: "He is a player that we can build our team around, which is why I was so keen to bring him here, and one of the most pleasing aspects for me is that we have signed him despite interest from some other big, big teams. "Some thought it was a done deal that he would be heading elsewhere, but we got the player which is good, as it shows that we want to go places, to do better. A signing like that can only help us as we try to bring more players in. "When I first sat down with the chairman, Craig was at the top of my list, our number one target, so I am absolutely delighted to have signed him. "He is going to be a key player for us. He was the best player in League One last year, he scored the most goals, he scored in the play-off final, and he's got everything we need to help make our strike-force one of the best."
