West Ham face an absolutely huge game against Everton at the London Stadium on Saturday.
The Hammers currently sit in 16th spot in the Premier League table, just one point clear of the drop zone.
And defeat to Everton this weekend would really damage West Ham’s hopes of survival.
In order to beat the Toffees, David Moyes has to make some changes against his former club.
Firstly, the 56-year-old must revert to a back four, and use the system that worked so well against Bournemouth on New Year’s Day.
After the win over the Cherries, the Hammers switched to a 3-5-2 against Gillingham in the FA Cup and Sheffield United in the Premier League.
It was clear and obvious that it was an unfamiliar system to the players, however.
West Ham must go back to basics, and a 4-4-2 formation would be a good place to start.
Secondly, Moyes must drop Fabian Balbuena and replace him with Issa Diop.
The 28-year-old joined the Hammers from Corinthians in the summer of 2018, for a fee believed to be worth £6.5 million, according to Sky Sports.
The Paraguayan made a decent start to life at the London Stadium. But he has looked shaky this season, aside from a couple of impressive displays.
Balbuena possesses no pace whatsoever, and his lack of mobility is frightening at times.
Time for Moyes to mix things up
David Martin received plenty of criticism for his part in the goal that West Ham conceded against Sheffield United on Friday night. But Balbuena was equally to blame. He was so flat-footed, and his lack of athleticism and ability to change direction played a pivotal role in Oli McBurnie’s goal for the Blades.
It’s time for the 28-year-old to be taken out fo the team. And he should be replaced by the younger, quicker and more mobile Issa Diop.
Everton have so much pace in their attack. The prospect fo Balbuena lining up against the likes of Richarlison, Dominic Calvert-Lewin and Theo Walcott is a very scary one indeed.
And because of that reason alone, Moyes should drop the Paraguay international in favour of his younger, more athletic teammate.
