Sierra Leone defender who is presently undergoing trials with Portsmouth, Mustapha Dumbuya, has expressed his desire to sign for the League One club despite the increasing financial difficulties before them.

The former Doncaster defender joined Pompey's pre-season training camp in Spain and has featured in all of their friendly matches.

Pompey boss, Michael Appleton, made no secret of his desire to sign the full-back and has been boosted by the 24-year-old's promise to sign a deal when the time comes.

With Portsmouth still unable to sign new players as they have been given until August 10th to sort out their financial problems or go out of business, Dumbuya maintained that he is willing to sign for the club.

"I will sign here. I have given the manager my word and he has given me his word," Dumbuya told the Portsmouth News. "The manager attracted me with the way he spoke about the club and I liked his ambitions. Hopefully things will get sorted out and it can move on. It was always going to be a waiting game; he told me that from the start. Patience pays dividends at the end of the day."

The player went on to express his disappointment at his former club's manager, Dean Saunders, who he said failed to live up to his promise in offering him a new deal this summer after his current contract expired.

He said: "My time there (Doncaster) went really well and I was part of a successful team, but the new manager who came in had a different style of play and I didn't fit into that.

"Before the end of the season, he promised me a new deal and over the summer I thought I was going to get a call from him but I didn't get anything. It is great to be wanted by Portsmouth, though."

Dumbuya made four appearances for Rovers before the arrival of Saunders in September and he also spent time out on loan at Crystal Palace at the start of this year. He is yet to make his Leone Stars debut.
