McLaren will no doubt improve, and more quickly than Manor, so I wouldn’t include them in Manor’s chances, but with a new car being introduced later in the year, along with the upgrade to 2015 Ferrari engines, I can imagine we will see a slight improvement. However, I still think they will remain at the back of the grid for the whole season.
I think their best result will simply be whatever race has the most retirements (excluding Australia of course), provided at least one car finishes. Obviously their position will depend on how many retirements there are. Monaco could be their best shot, as they proved last year.
