Notts County sign Mustapha Dumbuya and Alan Sheehan

Notts County have signed Sierra Leone international right-back Mustapha Dumbuya and agreed a new two-year deal with left-back Alan Sheehan.

Dumbuya, 25, was born in Sierra Leone but moved to England at an early age and joined Doncaster Rovers in 2009 after a spell in non-league football.

A loan spell with Crystal Palace was followed by a move to Portsmouth and, most recently, a stint at Crawley Town.

Mustapha will add an extra dimension to our play. He is quick, he can play in a number of positions and he can be a threat down the wing, but is also a good defender

Sheehan, 26, had said he was eager to sign a new contract.

"I'm delighted to be here and we've got an exciting year coming up, where hopefully we can kick on from last season," Sheehan told the club website.

Magpies boss Chris Kiwomya was delighted to bring in Dumbuya.

"I've spoken to Mustapha and he has the right attitude, he wants to play for this club and he wants to do well here," Kiwomya said.

"That's key for me - I need players here who want to be here, who want to succeed for this club, work for their team-mates and for the fans who pay their money to come and watch them every week.

"Mustapha will add an extra dimension to our play. He is quick, he can play in a number of positions and he can be a threat down the wing, but is also a good defender.

"He should fit in well to the style of play that I will be looking to play this season."
