The issue with Frank is he hasn't enough experience at all. At Derby he basically had money thrown at him, and he took them from 6th to 6th. At Chelsea, his best work came under a transfer ban, when he was forced to work with their academy players. He thrived there. The issues again came when he was spending, and he brought in dross like Werner. The difference between us and Chelsea is that their academy is full of great talent. Ours isn't, other than a few bright sparks like Gordon. The fact that Tuchel walked in and won the CL with the same squad Lampard had in 8th would suggest Lampard is tactically average at best.
I genuinely don't think he knows what to do. He wants to desperately play a certain type of football, but doesn't have the means to do it. A decent manager would take a look at the bones he's got and find the best system for them. The best thing he could do is play boring, defensive football. Yeah, none of us want 10 men behind the ball, but if it keeps us up, so be it. The ends justify the means.
And coming out bollocking the players and saying we conceded "two average goals and a fluke goal" and that the tactics were spot on. Come on! I agree this group of players are a gutless bunch of cowards, but the tactics were still wrong! If we're too rubbish to score goals, at least make us hard to beat. Focus on defence and set pieces. It's not hard, is it?
