Nathan Tyson: Experienced striker wanted by Port Vale boss Bruno Ribeiro

Nathan Tyson scored 21 goals in 80 games for Doncaster Rovers

Port Vale boss Bruno Ribeiro says he wants to add former Nottingham Forest and Doncaster Rovers striker Nathan Tyson to his new-look squad.

Tyson, 34, who left Rovers following their relegation to League Two last season, is on trial with Vale.

"I like Tyson a lot, it's the chairman's (Norman Smurthwaite) decision but I want him to stay," Ribeiro told BBC Radio Stoke.

Ribeiro has already signed 12 new players since taking over in June.

Tyson started his career at Reading and made a series of loan moves before establishing himself with League Two side Wycombe, where he scored 42 goals in 78 league appearances.

He moved to Forest in January 2006, following an initial loan spell with the Reds, and then made a switch across the East Midlands to Derby County after five and a half seasons at the City Ground.

Further spells with Millwall, Blackpool, Fleetwood and Notts County followed before joining Doncaster in July 2014.

Bruno Ribeiro played for Leeds United and Sheffield United in the late 1990s and early 2000s

An appearance from the bench in Port Vales pre-season game against Wolves on Saturday, was enough to convince Ribeiro that Tyson will add a new dimension to his rebuilt squad.

"He's experienced and has good quality," Ribeiro said. "He has something different to the other strikers we have here - he can play as a winger and can also come inside.

"We'll have to see whether we have the money or not for him."

Meanwhile, Ribeiro has said long-serving winger Chris Birchall is unlikely to stay at the club.

The Trinidad and Tobago international, 32, who spent the first five years of his career at Vale before returning in January 2013, was offered a new contract on reduced terms at the end of last season, but is set to move on.
