When a manager is restricted by FFP then net spend is a mitigating circumstance as he started with nowt. Sell to buy makes net spend relevant and is a good argument. Allardyce didn't have the FFP problem but in the long term added to the problem especially with Tosun
Would tosun have fit inside an allardyce team once he was given money to build it rather than what we did afterwards which created the problem?
The pro and con of having allardyce here is a often tred conversation but the club did sack him extremely quickly rendering the likes of tosun surplus to requirements. Much the same way Silva's players didn't fit that well into ancelotti and the cumulation of the squad of several sacked managers not fitting into benitez and lampard side.
Teams like Chelsea sign players in spite of the manager so the next one can utilise the players better , we did the opposite and signed players to fit one specific system and then sacked the man who's system it was. Or we signed players based on agents suggestion above everyone's head and they have never fit until we got lucky.
For what it is worth allardyce would have did more than just top half finish as he would have changed the club from the inside the same way benitez wanted to. We may have even been in a better state now if we had backed him.
