I would guess that Fox won't be earning as much as Gillespie but don't know if the difference will be that significant. We've already brought in two defenders this summer and I'm guessing that whatever we're paying O'Hara will be costing more than the proportion of his wages we covered while he was on loan. How much we've saved by not having Manzinga and Ilic on the wage bill, I don't know but again I don't imagine it'll be a massive amount.
If we're going to persevere with 433 with two wingers, then four centre forwards seems excessive. Lang may well be able to play on the wing but Long is a centre forward, nothing else. The same has to be said of White and Watt. Long or Lang, not both. Have never seen Lang play but didn't really rate Long so not fussed. Let's not waste a wage on a fourth striker though. .
