If we can finish top half this season, or there or there abouts, it's been a brilliant step forward. There's no reason we can't given what we've seen and the quality of player we have at the club.
Like Rosie said, we need to look at the squad we have before we decide what we need, we still haven't seen M'Hand or Traore, or much of Vale or Simons. Presumably Scott, Williams, Cannon, C. Jones and Smith will be allowed to move on. Still have Allahyar and Tetteh to come back too.
His first priority should be tying Doc down to a new contract, we don't want that dragging on. We have the option, but it would really show commitment in the long term and his best years are still ahead of him. If he gets a call up to a Scotland or Ireland squad he might start attracting unwanted attention. Pelkas has a clause for a permanent fee, get him signed up. Despite what many have said about him, I'd also be buying Baxter. A 23 year old keeper with two seasons of Championship football is a prized asset. Salah we will have to wait and see, there's a clause there (a pretty affordable, less than a million pounds one) and given his potential (and the astonishment from Arsenal's fans) it's tempting, but without seeing him play I couldn't make a call.
