Hardly. If he has a long term injury he has to be managed appropriately, there's hardly any point him playing 90 minutes 3 games in a row then being out for a month.
It may not just be a case of 'improving our coaching'. IIRC he failed a medical before joining us and seems to have long term injury problems that reoccur now and then. It may be a case of play 20/30 mins at 100% or play the whole game at 50% or something similar.
