I don't think his purchases have done that bad.
El Ahmadi has improved a little and Vlaar has improved a lot.
Lowton and Sylla have admittedly gone backwards
Westwood at the very least hasn't declined IMO
Bennett's been injured for most of the season
Benteke's a strange one. He has declined but I think some of the factors are out of Lambert's control.
Too early to judge this summer's signings.
Guzan and Delph too, Clark for sure and maybe even Baker
I will give you Guzan, but did he didnt sign Delph, Clark or Baker.
