Former Manchester United defender Gary Neville says Liverpool attacking midfielder Florian Wirtz "needs to sort himself out" and believes people have been "kind" to him and fellow big-money signing Alexander Isak after lacklustre performances for the Reds. Both Wirtz and Isak cost the Merseyside club more than £100m each in last summer's transfer window and they have failed to set the world alight since. The duo have come under increased scrutiny after failing to make an impact in Sunday's 2-2 draw against Newcastle United.
