I think Moyes will try to buy one more player before the window closes, and perhaps 1-2 loans (with options to buy next summer). If we get Oviedo, I don't think Moyes will have money to buy anymore unless they come for less than £1M. But another midfielder CM/RM on loan is plausible.
If we don't get anymore in, I will be slightly disappointed for a short while. But if I look back at this summerwindow with our current dealings... I'd be happy. Pienaar back for good will give us our lethal lefthandside back, Naismith and Mirallas have shown us their qualities already. With them our offence have seriously improved and our tightknit defence is still intact. Anymore first-11 signings are just going to be the icing on the cake.
Oviedo... £5M for a backup LB? I'm not sure that would be ideal, unless Moyes thinks Baines will leave this winter or next summer. Would prefer us to snap up another midfielder or two instead for those £5M.
