Seven-time World Champion Michael Schumacher is pleased to see Kimi Raikkonen link-up with Fernando Alonso at Ferrari for next season but believes it will be a volatile pairing.
"Ferrari with Fernando and Kimi, that sounds like an explosive mixture," Germany's Schumacher, who won five of his seven titles with Ferrari, told German daily Bild.
"For motor sport fans, it will certainly mean fireworks and for their rivals, a tough pairing to overcome.
"It will be exciting to watch."
On Wednesday, Finland's Raikkonen was presented as the team-mate of Spain's Alonso for next season and will return to Ferrari having driven for Lotus for the last two seasons.
Raikkonen, who is reported to earn around 20 million euros ($26.6 million) under his Ferrari contract, will replace Brazil's Felipe Massa, who is leaving Ferrari at the end of the current season.
