At the Chinese Grand Prix earlier this month, subtle Chelsea branding 'Out of the blue' featured on Sauber F1 team cars, and 'True Blue' continued the tease at the Bahrain race, leaving fans guessing as to its meaning. The image above features a 'Welcome Chelsea FC' message on the Sauber F1 team car, which will be used during testing in Italy tomorrow.
截取一段原文：在中国站的时候，有【Ture Blue】和【Out of the blue】的标语，而在巴林赛道的时候也有，让赛车球迷捉摸不透。明天的意大利测试赛，索伯车身会印有【'Welcome Chelsea FC】的标语。
