Sunderland have clinched the signing of Rennes striker Ola Toivonen on a season-long loan.

The 29-year-old began his career in his homeland with Degerfos IF before playing for Gothenburg and then Malmo.

He moved to PSV Eindhoven - where he played under current Sunderland boss Dick Advocaat - winning the KNVB Cup and Dutch Super Cup, before joining Rennes in January 2014.

Advocaat told the club's website: "I worked with Ola at PSV so I know him well.

"He is a national team player with a lot of experience, an attacking midfielder who can score goals and is good in the air - he will bring something different to the team."

Toivonen, who goes straight into the squad for this weekend's Premier League match with Aston Villa, also knows Sebastian Larsson and Jeremain Lens.

Toivonen said: "I worked with Dick Advocaat for one year at PSV and we [got] along very well, so I'm excited to work together again.

"I already knew Sebastian from the national team and we've played together for five or six years, and I also know Jeremain Lens from our two years together at PSV."
