After more than 3 years, Schumi - the most successfull and arguably the best driver ever - makes a comeback. Though it is only temporary to replace Massa who endured a horrible crash last week.
Since there is a ban on in-season testing, Schumacher’s first laps will be during the first practice session of the next GP. Therefore, I don’t think we should have very high hopes for his performances this year. If he can gain a few points with one or two podiums would be great in itself.
