I think Chelsea will qualify for the Europa Conference League phase because I see Chelsea as the strongest club in this qualifying round, Servette is a weak club so it is not difficult for Chelsea to beat them again in the second leg even though Chelsea is playing away, English clubs are always favorites in UEFA competitions, it is very embarrassing if Chelsea does not qualify it is a kind of insult to them, Chelsea's attacks have been very strong lately I think they will add a bigger aggregate in the second leg later.
In last two games, we have good performance from the Chelsea against Servette and Wolves after having results like these there is no doubt about their chances to have spot into main round of the Conference League after long time things are looking positive for them hopefully they will be having another good result in Switzerland with fix their spot into next main round this could be good for them.
Servette is having spot in middle of the Switzerland soccer league table with in last few games their performance is also not good as they can handle quality of Chelsea Cole Palmer and Madueke doing good job with Jackson is also having his name on goal scorers sheet as expected we have good results from the new coach Maresca but still his main target is having spot into top four of Premier League, but it is looking challenging.
