I don't want to be too critical of Frank because, like you, I know he is working with a collection of charlatans on the playing staff (not to mention on the board). There were mitigating factors that must be taken into account - just as they should have been with his predecessor. That said, his "statement" signings of Delle Ali and Donny van de Beek were big punts that have simply not worked out. He had almost no time in the window - but part of the attraction of his appointment was in his ability to bring in desperately needed reinforcements on the basis of his name recognition. They have bombed.
The lack of game management at Burnley was also unforgivable. At worst, we should have drawn that game. Some of his selections (Kenny, etc.) have killed us. People will say he has had little time to address these things - and I have some sympathy for this viewpoint - but his job was a salvage operation and he needed to produce a bounce through some form of alchemy associated with his personality/reputation, etc., in the absence of time and, let's face it, demonstrable proven coaching ability.
I wish him well tomorrow. But I see no benefit in supporting Team Lampard when the club is plummeting to oblivion.
