Struggling Portsmouth have introduced record signing Benjani Mwaruwari and the new co-owner of the club Alexandre Gaydamak to the Fratton park faithful.

Portsmouth will pay French club AJ Auxerre a club record £4.1 million for 27-year-old Zimbabwean striker Mwaruwari, whose move to Pompey is still subject to a medical and an international clearance.

French national Gaydamak, 29, will work alongside chairman Milan Mandaric. He is expected to bring substantial funds to the club although he declined to specify the size of his potential investment at today's news conference.

His recruitment though, is a boost to manager Harry Redknapp's hopes of strengthening his squad for their fight against relegation from the Premiership. Portsmouth are third-from-bottom, two points adrift of the next team above them.

Gaydamak said he was thrilled and happy to have joined the Portsmouth cause.

"My ambition for the football club first and foremost at this stage is to stay in the Premiership," he said. "Then at the end of the season in accordance with the results we will see what we will do.

However, Gaydamak rejected comparisons with Chelsea's billionaire Russian owner Roman Abramovich and the suggestion that he would be the club's saviour.

"I see myself as a person who saw an opportunity and a very strong challenge, definitely not the saviour," he added."I am here for the long term. I am here to build something big."

He was, however, also forced to fend off several questions from reporters concerning his billionaire Russian father Arkady Gaydamak, who was questioned by Israeli police in connection with an international money-laundering probe on Wednesday.

Gaydamak stressed his father had no involvement in his deal to buy into Pompey.

"Portsmouth Football Club is a business I am investing in. There is no relationship between my father and the football club," he said.

"It is my money from 10 years of working. It is completely my money [from] working in finance and real estate."

Mandaric said further player signings were on the cards. "We will see additional players...we are supporting our manager 100 per cent and his needs," he said.

Mwaruwari revealed that he had turned down the opportunity to join French club Olympique Marseille to join Portsmouth.

"I had a chance to join Marseille but I preferred to come here because I speak English and my French was still bad," he said with a smile.

On Wednesday Portsmouth signed Polish striker Emmanuel Olisadebe from Greek side Panathinaikos until the end of the season.
