Some Swansea fans on another forum have said that their top priority this window anyway was a left back, as they never replaced Ben Davies after he left, so I imagine they will go for this regardless of whether Taylor leaves or not. They also said that they also needed a right back, so even if they bring in Naughton I imagine they will continue to try and sign Olsson.
In an ideal world we would keep all our first-team players, so that we can keep moving forwards without any drastic changes to the team. However, if we can get £5m for Olsson I'd be relatively happy with that. More than that and I'd be pretty pleased. He was excellent last season, but this season for whatever reason he hasn't quite lived up to the standards he set himself last campaign. I really like him, but he has been suspect defensively much more regularly than he was last season, so if we can get £5m and an adequate replacement it is certainly something I would be in favour of.
Didn't we reject a bid of £4m from West Ham in the summer? If so then you'd think that we could get more for him now.
