If it costs you 2 million to sack someone, would you rather sack them or would you pay for his seat at HRT which would cost 10 million.
Liuzzi I understand brought some cash to the team too, so I think the costing for FI is not paying a settlement, but in fact losing some cash through sponsors.
Also consider that no team will sign a B-class driver into a cast iron contract without some escape clause. Liuzzi is way better than I'll ever be but he aint gravy on the F1 circuit.
Mercedes will probably be the sugar daddy for Di resta, Just as Liuzzi had his backers(unsourced...but im going by memory, feel free to pull me up here).
The HRT seat will be on a cost per race basis that will see Liuzzi miss races out, as he cannot afford to race over the whole season. Business as usual at HRT then!
The real crux of the matter here is wether Force India feel that Di resta is £10 million better than Liuzzi. And knowing Vijay Mallaya's reputation regards budgets, there is no way you can say that he would accept this.
If Di resta was a full second faster than Liuzzi, fair enough. But hes not, mere tenths seperated their times last season.
Also, where is force India going to find 8 million from? Thats about 15% percent blown for the season.
For me it just doesnt add up.
