There is no doubt Koeman was a big influence on persisting with Sigurdsson. It does not necessarily directly correlate with not looking for a striker, perhaps key people's time was taken up negotiating with Swansea, but I consider it equally likely that is nothing to do with it, we've just struggled to identify an attainable target or negotiations we don't know about are in progess.
Fair points but a major part of this window will be judged on how we have replaced the goals of the one top drawer player we had in the squad, which we let go for a huge amount of money. Saying we've spread them around is valid to a degree but at some point you need a reliable front man to play off and contribute himself.
Of course we may still do that in the 36 hours left in the window but failure to do it, after knowing Lukaku was wanting to go for over a year and then eventually going 6 weeks ago, is pretty poor whichever way you look at it.
