West Ham manager Julen Lopetegui has reportedly been warned he will be sacked if results do not improve.
The Hammers are floundering in 14th in the Premier League and sank to a 3-0 pummelling at Nottingham Forest on Saturday, with Edson Alvarez getting sent off.
It was the second time in three weeks they have suffered a battering as they also lost 4-1 at Tottenham, though they did beat Manchester United 2-1.
This is the second occasion Lopetegui has been cautioned about the team's form by his bosses and there is particular pressure on Saturday's home game against Everton, according to The Times.
