In an interview which the Brazilian sports daily Lance published Wednesday, Massa argued that it will be easier for his team to get good results next season if Lewis Hamilton has a new partner in McLaren.
Hamilton leads the Formula 1 drivers' championship ahead of the last race, the Brazilian Grand Prix on Sunday, with a four-point advantage over team mate and bitter rival Alonso and a seven-point gap on Ferrari's Kimi Raikkonen.
"We cheer for that to happen," Massa said of rumours about Alonso's imminent exit from the British-German team. "A team with Alonso and Hamilton together is very strong. With both racing separately, our chances increase."
Although he no longer stands a chance in the drivers' championship, the Brazilian stressed that he hopes to do the same as last year and win his home GP in Sao Paulo this weekend.
"I will do my best to get ahead and win. There is no other strategy, unless the chance appears for Kimi to win the championship. (In that case) I will try to help however necessary, because the team has been honest with us both throughout the season," Massa said.
The Brazilian, who won three races this season and has just agreed a deat to remain at Ferrari until the end of the 2010 season, regretted the espionage scandal around McLaren this year.
"It was neither good nor pretty. We try to get our sport to be ever clean," Massa said.
