He told TV Globo: "I know both Fernando and Kimi on and off the track and I rate them as excellent drivers, but I'm afraid they will collide when sharing the team."I told the bosses to breathe as much as possible while they still can because it will be hard for them to breathe in the 2014 season."Button, part of F1's most recent team of champions with Lewis Hamilton at McLaren until the end of 2012 when Hamilton moved to Mercedes, was keen to see how the new Ferrari pairing got on.'INTERESTING ATMOSPHERE'"It's going to be an interesting atmosphere between those two, especially if Kimi is as quick as Fernando," he said. "If Kimi starts out-qualifying Fernando that would be a big one because Fernando is not the quickest guy but as a package he's exceptional, his race pace, he's very good at thinking about situations so he's going to be a tough guy for Kimi to beat."It's fun for us watching from the outside... does it make the team stronger? I personally don't think it does," added the 2009 F1 champion.Massa has been inconsistent since he came back after a life-threatening crash during the 2009 Hungarian GP and has not won for Ferrari since he almost took the championship at the 2008 Brazilian GP.Raikkonen has enjoyed a record run in the points, which ended in Belgium during August 2013, since returning to F1 with Lotus in 2012 after a two-year absence. His pairing with Alonso, a double F1 champion, promises points but also fireworks.Button's McLaren team mate Sergio Perez expected them to be strong rivals for the other teams, however. "I think it will be very interesting for all of us to see how they get on, both of them. I think Fernando and Kimi will be a tough couple to beat."
