Vitor Pereira says he has full trust in Evangelos Marinakis despite becoming the fourth manager of Nottingham Forest this season.

The former Wolverhampton Wanderers boss has signed an 18-month deal at the City Ground after Sean Dyche followed Nuno Espirito Santo and Ange Postecoglou in being dismissed by Marinakis since August.

Pereira is no stranger to working under the Forest owner, having previously enjoyed a successful spell together at Greek giants Olympiacos.

“He is ambitious, he wants to win,” Pereira said at his unveiling on Tuesday. “He’s emotional — I know him very well.

“The conversation was about our time at Olympiacos. I remember the energy and the fire we created. In Greece there is a fire inside; they like to see that energy.

“He asked me to be myself. He liked the way that when we worked together we won the league and cup. It was in the middle of the season and we created a good relationship. He trusts my work, I trust his personality.”

Pereira takes charge of a side sitting just three points above the relegation zone with 12 Premier League matches remaining. The 57-year-old guided Wolves away from trouble last season but was dismissed in November after a 10-game winless start to the current campaign.

He will oversee his first match in Thursday’s Europa League play-off trip to Fenerbahce and is confident Forest possess the quality to secure survival.

“This is a difficult season for the players because it’s different methodologies, different managers,” Pereira added. “It’s not easy, but I accepted this job because I believe in the quality of the players, the potential of this club and the ambition of the president.

“Of course, I believe it’s possible to stay up. I believe we can get points, results and quality in the games.”
