Swansea City's summer transfer window is already under way, with the club looking to strengthen their squad. The capture of Stephen Welsh on a free transfer has given some welcome depth to Vitor Matos' centre-back options heading into the new season. The club are also looking to recruit a left-back and one, ideally two, wingers over the next few weeks. The appointment of a new sporting director might well help grease a few wheels, but finding a successor to former head of recruitment Adam Worth, who left in April, is just one of several loose ends that will need to be tied up this summer. The futures of Zan Vipotnik and Ethan Galbraith are likely to fill up most of the column inches over the next few months, and some Swans fans might well be starting to roll their eyes in unease at some of the headlines that have already been written about the pair in recent weeks. Speculation around Vipotnik has, in fairness, been bubbling away ever since January, when then Premier League side West Ham United were among the clubs to look at him. Swansea showed little appetite in selling, as evidenced by their £15m valuation, which was clearly enough to ward off any potential suitors. Then again, a hatful of goals, and a Golden Boot on his shelf, means Vipotnik's list of admirers has continued to grow. Sporting are the latest to be linked, while fellow Portuguese giants Benfica have held initial conversations about his situation. Neither are likely to be alone. Having been relegated, there's every chance the Slovenian's record in the Championship will crystalise West Ham's interest, particularly as they bid to mount a challenge back to the Premier League. The resulting headlines will make for uncomfortable reading for many Swans fans, but City are arguably the ones holding most of the cards here. Of course, the club isn't in a position to turn down a big-money offer, but they aren't, on the face of it, under too much pressure to sell. Vipotnik recently penned an improved new deal with the club towards the end of the season, a move many will interpret as a bid to strengthen their hand rather than a genuine declaration of commitment to Matos and his cause. But even so, Vipotnik's value in the market has surely leapt up as a result - and will only soar further should interest continue to build. The only thing that drives a price more than goals is a bidding war. The same, to an extent, can perhaps be said for Galbraith, although the Northern Irishman's situation is perhaps a little different. He already has two years to run on his current deal, and there's the option of another 12 months at the end of that, which means there's already little immediate pressure on the club to sell - if indeed they are at all interested in doing so, which in itself is a debateable point. But the substandard first offer in talks over a new and improved deal seem to have muddied the waters a little. Indeed, the opening offer put to him and his camp was well below that of the club's top earners. The stand-off between the two parties has created a vacuum that has inevitably been filled with speculation, although the truth is interest has been in the background for some time. Even when he signed for the Swans, Galbraith's future was always going to be a topic of discussion, given his impressive performances and the fact that he was only on a short-term deal. Now, with the summer transfer window open, it's likely that Galbraith's future will be the subject of much speculation and debate.
