Thing is we are only 5 points off the top, so why wait? Getting someone in right now would give us our best chance of going up, whereas if we leave it too long we won't have a chance of catching up.
Overall, Bruce has failed to address a blatant problem with the defence and his cluelessness he showed when talking about Forestieri just showed that he doesn't prepare properly. This goes beyond results, it's just monumentally poor management all round.
