Sam Allardyce has seen a major turnover in players since he took over as manager of West Ham 16 months ago but is delighted with the team spirit at Upton Park.
The 58-year-old guided the Hammers back to the top flight in his first season in charge and they now sit seventh in the Barclays Premier League eight games into the season.
"The team had to have an overhaul because of the financial devastation of getting relegated. I mean it's that plain and simple," he said.
