Omerod and the Arsenal kid will be a waste of time as we could only get them on loan and would not be worth it.
Let's stick with Hart & Knight up front, if we need to change things to add another dimension to our play then throw Virgo back up front. For the first few games when Virgo was a striker we benefited as it took the opposition by surprise but then that wore off. Now we have him back in defence we can move him back up-front when needs be and it will be a "surprise" again. So, perhaps we do not need to sign another striker.
