Actually I think the key to the improvement is playing Davies he had kept Barry out more, Barryis a good footballer but lacks pace and that has hurt us when he has been playing. Also Snides has help massively too. So whether it's Bolasie, mirallas or Lookman I don't really think results would have been much different, the midfield was the problem as Koeman seems to have sorted it.
midfield, fitness and a desire to put the effort in imo. Since just before the turn of the year, if we'd had Bolasie fit and rotating/challenging for the spare left hand slot with Mirallas, Lookman it would only be of benefit to us.
He was not only unlucky with the injury but we were in absolutely dire form and imo he was someone who was struggling for former himself but was still putting in a great shift and still trying the unexpected.
