Maybe Chelsea is only slightly ahead with their current performance but that doesn't mean they can win easily against Newcastle.
We know Newcastle is also a difficult club, so no one is expecting the match to be a easy win for Chelsea. We all know Chelsea have been playing well lately, but I am sure they are still going to give Chelsea a tough time. But if we can compare the way the two clubs have been playing lately, Chelsea should be able to win the match. Newcastle lost their last two matches, the last one being against Bournemouth and their match against Dortmund in the Champions League. But most people didn’t expect Chelsea to win and draw their last two matches. Chelsea played a draw against Manchester City, which was very surprising to everyone, and they won against Tottenham. With Chelsea's performance, they should be able to win the match.
