According to a report published by the Telegraph, Rafa Benitez, Marco Silva and David Wagner are managerial targets of West Ham.
David Moyes is unlikely to remain manager of the club beyond this season even if they do manage to avoid relegation.
The backroom at the East London club is said to be tense after they failed to recruit a number of January targets.
Though the club signed Joao Mario and Jordan Hugill, they failed in their pursuit of Islam Slimani and Ibrahim Amadou.
Meanwhile Benitez is unsettled at Newcastle and has previously criticized the club publically for failing to back him sufficiently in the transfer market.
The Spaniard is also likely to be unhappy after the Magpies had a rather underwhelming January transfer window, especially considering that they are relegation contenders.
If the Hammers do manage to recruit him, it will be a major coup. Though Silva and Wagner are two talented managers, they do not have the experience and reputation of Benitez.
