Rafael Benitez has nine games remaining to save Newcastle United from the drop.
The Spaniard took over from Steve McClaren last week, and he has only had a minimal time to work with the North East side so far.
Benitez has taken charge of his first few training sessions, and he also led his side at the King Power Stadium, as they lost 1-0 to Leicester City.
The defeat against the Foxes was a disappointment, but Sissoko still speaks highly of the former Real Madrid boss’s managerial style.
“We trained three sessions with him, it was short but good,” Sissoko said. “He brings his experience and we will work this week and the manager can help us to stay in the Premier League next season.
“He said he knows the players in this team, we have some good team with good players which is why he came here. He believes we will stay in the Premier League, we have to work hard every game.”
Benitez effectively has nine games left to save Newcastle from relegation.
The 55-year-old has an exit-clause in his contract, which will allow him an easy escape should Newcastle go down.
At the moment the Magpies are set for the drop, as they sit in 19th place in the Premier League table.
Newcastle are one point adrift of safety, but they do take on Sunderland at the weekend, and a win in that fixture could take them out of the drop zone.
