SAO PAULO, Oct 21 (Reuters) - Germany's Ralf Schumacher drew a blank in Brazil on Sunday in his last Formula One race for Toyota.

The younger brother of Ferrari's retired seven-times world champion Michael Schumacher, who said farewell to the sport at Interlagos last year, finished a disappointing 11th and lapped by Ferrari's race winner and new champion Kimi Raikkonen.

"I have enjoyed my time here and I am looking forward to seeing some of the guys for a drink in the future," said
Schumacher.

The 32-year-old German's future remains uncertain even if he has said repeatedly that he expects to be in Formula One next season.

Toyota presented the driver with a 10kg cake before the race as well as a signed rear wing end plate from his car.

"Ralf brought valuable experience to the team and helped us move forward," team principal Tadashi Yamashina said in a statement.

"He has worked well and in many ways we are sorry our relationship is coming to an end. However, circumstances change and we wish Ralf all the best in his future career."

Schumacher won six races, all with Williams, before joining Toyota in 2005. In three seasons with them, he took three podium finishes, one pole position and scored 70 points.
