Thought there was an interesting point in the Arsecast today, unsurprisingly it's in line with something I believe😂, but I think it was articulated well. Mainly as noted above that we've not taken enough chances in our attacking recruitment as it's always a gamble the idea you can find a guaranteed top player is unrealistic approach.
They cited Liverpool signings since 2015 which includes Ings, Benteke and plenty of others who flopped but equally Mane, Jota, Salah. Also made the point both Henry and Salah when they were signed nobody knew they would become the elite players they did. There was an element of luck in that and our approach recently just hasn't been diversified enough and willing to chance it to try to improve.
Equally as mentioned here we have taken more risks in recruiting defensive positions with no guarantee so it doesn't seem to be a universal approach so why have we fixated on it for attackers.
