Ambitious Eredivisie outfit Vitesse have decided to part company with head coach Theo Bos with immediate effect in the wake of the Arnhem side's disappointing start to the 2010-11 league campaign.
Vitesse have set their sights on European qualification this season, but are battling against relegation instead at the moment. They sit 16th in the league table with only eight points from nine games.
"It was a tough decision for us to let go of Theo Bos. We're thankful for all the good work he has done at this club. He'll always be a real Vitesse man and he's always welcome here," said technical director Ted van Leeuwen in a press conference.
The 45-year-old Bos was appointed Vitesse coach in January 2009, but failed to guide the Arnhem side to the upper echelons of the table. Bos has been in charge of Vitesse in 63 official games and managed to win only 19 matches during his spell in charge.
Vitesse are expected to appoint a caretaker boss in the upcoming hours before starting the search for a permanent replacement.
