Currently, Newcastle's winning streak is far above Chelsea's. I don't think one will prefer Chelsea above Newcastle when it comes to betting slips. If I were in such a position I will choose Newcastle as I believe many others will.
Speaking about being able to keep the position, I don't. Think Newcastle will be weak in the remaining half of the season because currently, the team also has big hands in the transfer market even with a stable team, I believe they will be continuously bent on doing.
Based on the results that are clearly visible in the temporary standings table, indeed, yes, Newcastle is far above Chelsea. So a lot of people will look at Newcastle more than Chelsea, but that doesn't mean Chelsea can't bounce back for the rest of the season generally still have time to do very well. But Chelsea also have to involve themselves into the transfer market in terms of targeting the players they need in certain lines or in lines that are considered very weak.
