The Hammers have had a tough start to the season and Pellegrini has failed to get the best out of his squad so far.
If that continues, the Chilean might need replacing. The Hammers should look to make their decision fast and get Benitez on board if the Spaniard is willing to return to the Premier League.
Recently, Tottenham replaced Mauricio Pochettino after a poor start to the season. The Londoners moved swiftly to secure the services of a proven winner in Jose Mourinho.
West Ham should take note of that and do something similar.
