Yes, they'll likely have the money to sack him. My post was in response to the post below whereby sacking him, we'll be limited by what we can use to recruit.
This is because of Lampard's severance, where we'll have to pay the remaining portion of his contract, or at least a large part of it, depending on terms.
We ended up paying Koeman, Silva and others after they were sacked for the above, which is all well documented. So basic maths would suggest:
Pot - Lampard's wages > Pot - Lampard's wages - new manager's wages; we may be able to sack him, but will we have the money to get a decent man in.
