I'd recommend repeating the level as well. But if your race is very close and a climb into a CL spot is possible, the following are a few questions, just to create some food for thought.

How close to 4th place are you? How close to 3rd? How far ahead of you are the teams in 5th through 7th? If you wish to push, you'll have to not only catch 4th, but also hope a team in 5th through 7th doesn't finish strong. If 2nd/3rd are within like 1 point of 4th, your odds are better. But remember, you're going to have to climb over 4 teams in 5 days.

Level 2 champions league is usually very easy, with only a very few managers being active.
