Can't tell whether all the stick aimed at Pickford is serious or not. He's clearly a very good goalkeeper but still learning his trade, he's only 23 or so. Alisson made a huge fuck up last weekend, his second of the season, Leno has made several fuck ups and hasn't even played the full season so far, Lloris constantly makes howlers, none of those get the attention Pickford does whenever he has a poor game or makes a mistake.
That's the poisoned chalice of being "England's number one", unless everything you do is world class you get absolutely slated. Even genuine world class players like Rooney, Ferdinand, Scholes, Gerrard, Kane have never been held to the same standards as Seaman, Robinson, Hart, Pickford over the years. It's one of those truly baffling things.
Defensively we started poorly, sorted it out when Keane and Zouma got a run together. Then Mina had to come in when Zouma was unavailable against Chelsea, and while all three of them then played well for a few games regardless of who played, keeping a clean sheet at Stamford Bridge and all but shutting out Liverpool at Anfield, it disrupted the momentum of an established partnership and the chopping and changing has caught up with us. Coleman is also declining by the week and Gueye has been injured in the last two games against City and Spurs leaving us with no defensive cover in midfield and no balance as a result. The defensive side is a concern, and there are underlying issues but there are also specific circumstances making it look worse than it is.
At the end of the day, nobody can expect any manager to turn an Allardyce side into Barcelona in the space of four months. For example, Klopp took two and a half years to sort out Liverpool's defensive issues.
