Adrian was somewhat of a cult figure at West Ham.
The Hammers fans absolutely loved the Spaniard.
But his love affair in east London ended when he left on a free transfer to join Liverpool in the summer of 2019.
And what a huge mistake that now seems to be from West Ham. In fact, it is one that could end up costing them their Premier League status.
Lukasz Fabianski missed three months of the season from September to December, with the hapless Roberto filling in for the Pole, and the rest is history.
The 34-year-old Spaniard was a total disaster, and he was eventually shipped out on loan to Alaves in January.
His stats make for pretty grim reading.
In eight Premier League games this season, Roberto scored one own goal and made two errors leading to goals for the opposition. He conceded 2.125 goals per game on average and kept zero clean sheets. The Spaniard made zero high claims and completed an average of just 6.125 accurate long balls per game (premierleague.com).
Compare those numbers to Adrian’s 2017/18 campaign at West Ham.
The Liverpool stopper scored zero own goals and made no errors leading to goals for the opposition. He conceded 1.53 goals per game on average and kept six clean sheets. The Spaniard made nine high claims and completed an average of 9.16 accurate long balls per game (premierleague.com).
The difference is clear and obvious. Had the Hammers kept hold of Adrian, it is fair to argue that they would not be anywhere near the relegation zone now.
His contract had expired, sure. But West Ham should have done more to tie him down to a new deal in the final year leading up to the end of his contract.
And the east London outfit might just end up paying a very heavy price for that mistake.
