Good enough for Chelsea, they've managed to record two wins, one in the EPL and the other in the UCl. They might manage to pick up the pace from there. The goal for Chelsea now is no longer about contesting for the league trophy but, to regain there spot in the league as an elite team and that means, they've got to fight for the top 5 at least, to make it into the Europa because, a UCL qualification is very unlikely.
In Premier League, they must continue it and must see bad performances from Tottenham, Liverpool and Newcastle United to move up and take over positions of those clubs. Maintaining their own good form is already hard enough and getting support by bad performances of competitors is more difficult. Combine two conditions, it looks very impossible to happen for Chelsea in the last 13 matches in Premier League.
8 points are far but Chelsea will have to beat all three other clubs above them, that is not easy. If it is only one competitor to beat with 8 point gap, Chelsea can do it.
Against Leicester City should be an opportunity for Chelsea to improve its performance this season in the Premier League. After all, Chelsea's players must show interest so they don't continue to be stuck in 10th place.
Their players don't want to be sold in the summer transfer and they don't want to play in Europa League or Conference League next season. But between what they want and reality is big difference. Leicester City are no longer strong as they were two or three previous seasons but Chelsea also are no longer a club that can easily beat Leicester City.
