Sven has done very well in the transfer market since taking over. Acquiring Vassell, Danns and Nugent without paying fees. Also getting Bamba, St Ledger, Peltier and Schmeichel for a total outlay of £3-3.5m. On the other side, he's sold Hobbs and Fryatt for about £2m.
A top drawer defender and striker for serious cash are in the offing - ideally the likes of Mills and Maynard. In addition, I'd expect 3-4 loans of quality young premiership or overseas players.
All in all, he's on target to turn an okay Championship standard squad into the nucleus of a decent Premiership one at a transfer cost of less than £10M. Not bad in this day and age that.
Sven, Top and Vichai are all doing a terrific job.
