The Chilean and his staff were dismissed halfway through last season with West Ham having been dragged back into a relegation battle.
Pellegrini was backed significantly by the club, with the new accounts also detail £107.8m spent on new signings, though that figure included the arrivals of Tomas Soucek and Jarrod Bowen – who were signed following the former Manchester City man’s dismissal.
Almost half of that spending was on Sebastien Haller, the striker who was sold to Ajax at a considerable loss for £20m in January.
David Moyes was brought back to the club for a second spell to replace Pellegrini, the man who had been appointed following his first stint at the club.
Since returning to West Ham, Moyes has saved them from relegation for a second time and now has the Hammers in a race for Champions League qualification with the club fifth, two points behind Chelsea (fourth) but with a game in hamd over the Blues.
The cost to dismiss Pellegrini compares as relatively small when stacked up against other clubs. Arsenal forked out just over £10m when sacking Unai Emery and his staff.
