After Chelsea were dealt a humbling 1-0 defeat by relegation-threatened Queens Park Rangers on Wednesday, Benitez was forced to defend his decision to rest the likes of Eden Hazard, Juan Mata and Ramires.
Although the Spaniard is a well-known fan of squad rotation, Davids warned that Benitez's choices were unlikely to be appreciated by the players who were left out.
"Football players can be like predators. They will study you. They will try to find your weakness. It's ego," he explained in a column for the Daily Mail.
"The guys who are not playing will watch you like hawks. They will be on your case because they all want to play in their position no matter who the coach is."
The former Valencia manager took his place at the helm of Stamford Bridge on a six month contract after Blues owner Roman Abramovich sacked Champions League-winning boss Roberto Di Matteo. Despite rumours of Benitez's desire to be awarded the job on a permanent basis, Davids believed that none of the players perceived the Spaniard as their next full-time manager.
"If a player or a coach is under pressure and the others think he is going to leave there is only brief respect. That could be hard for Rafa Benitez, for example," he stated.
"I don't know what the dynamics are at Chelsea, but if everyone knows a manager is only going to be there for six months it's very hard."
Chelsea will begin their FA Cup title defence against Southampton on Saturday.
