May as well carry on the recuring theme at the moment 
Mclaren
Fernando Alonso
Juan Pablo Montoya
You may think it's confusing putting a double world champion in a worst team, but the 2007 season provides enough evidence to support this theory, and Montoya's one and a half years were fraught with injuries (tennis anyone) and squabbles with Ron Dennis which ended after the American Grand Prix after crashing into his team mate.
Ferrari
Nigel Mansell
Luca Badoer
Luca Badoers two races for Ferrari in 2009 must go down as two of the most awful races by any driver, particularly in the modern era, he was a long way off Raikkonen in both and in both races was languishing around at the back of the grid while his team mate was fighting for wins and podiums. As for Mansell, his 2 years were less than succesful with 'inferiority complex' issues in 1990 with Prost when he was told that his car had been switched with Prosts at times because Prost thought that Mansells was better
Williams
Alex Zanardi
Kuzuki Nakajima
Zanardi's only year at Williams was to be frank, abysmal, plagued by poor pace and reliability issues he rarely troubled the scorers and was unsurprisingly dropped for the young Jenson Button in 2000. Nakajima had promise but never delivered on it, his first race he crashed into his pit box and by 2009 he was being clearly outperformed by Rosberg and was replaced by Barrichello who is the reserve driver for this worst team.
Renault
Nelson Piquet Jr
Roman Grosjean
Ironically these are both the number 2 drivers from the disastrous 2009 campaign, Piquet was unpopular almost early on and apart from Germany where he nearly won, was hammered in the year and half at the team, and we all know why he is (im)famous after crashgate at Singapore in 2008. Grosjean is unlucky to be here in fairness but was as bad as Piquet when he was there and posed no trouble for Alonso, but he should be back and not on this list
Sauber
Jaques Villeuneve
Karl Wendlinger
It was clear pretty early on that Villeuneve signing for Sauber was a mistake and was under pressure almost imeddiately as he was the slowest of the Michelin runners after the opening races, a burst of pace later in the year only relieved the pressure temporairaly and after a poor 2006 season he was dropped after crashing at the German Grand Prix to be replaced by rookie Robert Kubica. Karl Wendlinger was a victim of circumstance really, his crash at Monaco in 1994 bore strong similarities to Perez's crash earlier this year and his performances after this were dissapointing and was dropped (twice) in 1995.
Minardi
Alex Yoong
Patrick Friesacher
Yoong spent the year either racing last or not racing at all because he wasn't anywhere near the 107% time, his only highlight was seventh at the Australian GP when very few cars finished. He was replaced by Davidson for 2 races and was eventually dropped at the end of the season. Friesacher only lasted half a year in 2005, while he did score 3 points that year, they were as a result of the farce that was the USGP where only 6 cars raced due to tyre problems on the Michilen cars. He was dropped due to financial problems
Jordan
Gergio Pantano
Takuma Sato
Both these one year 'wonder's showed glimpses but never the real deal, Sato was very raw, capable of lightning speed but crashed too often and was inconcistent so was sent to BAR the next year. Pantano spent all year at the back and not impressing anyone, his replacement Timo Glock at Canada scored points and he was eventually dropped after the Italian GP after 3 straight DNF's
Stewart/Jaguar/Red Bull
Antonio Pizzonia
Jan Magnussen
1 point in 2 years at Stewart sums up Magnussens spell at the team, despite being labelled as the best prospect since Senna, his faliure was embarrasing. He had more DNF's than finishes and was rarely in the top 10 when he finished and was eventually replaced by Verstappen. Pizzonia didn't even last a year at Jaguar in 2003 after failing to finish any higher than 9th he was dropped after the British Grand Prix.
Unfortunately my knowledge of older F1 teams is rather erm..... blank
So there are inevitably a lot of gaps that I have missed..
