I agree with you with Lyon's current situation, they are safe enough to be in the top 8-10, if they can be in a better ranking, but the obstacles that Lyon has to face in the remainder of this match are not easy for them to overcome and win consistently, because in the remaining 6 matches this season, 4 of them have to face clubs that are currently at the top and 2 of them face mediocre clubs and relegated clubs, so technically Lyon will face quite tough clubs in the remainder of this season, so it is impossible for Lyon to be ranked in the top 6 if Lyon is unable to beat these clubs even though the difference in points with the club that is ranked 6th is not too big.
And on Monday, Lyon will face Brest. This is quite a difficult match even though both clubs are in good form, but Brest looks more convincing to win the match compared to Lyon, but because the match is held at home, Lyon will get an advantage and will try hard so as not to disappoint their supporters, but I think the possible result for Lyon is to achieve a draw.
Lyon started the season on a very poor note but were able to pick up form and get themselves to the the top half of the table and sincerely the efforts of the board and players aren’t going unnoticed in this rise. Now they’re struggling to get into a spot for European competition next season but that will seem pretty difficult.
This is because the opponents they’ll be facing are real top teams who are also in a run for UCL football and with these teams what Lyon can try to get is at least a draw as the hope on getting full 3 points will really be a tough one. For such reasons i agree with you that they might not be able to go past 8th position.
On the other hand, determination and mentality is one big factor that will help this Lyon team succeed as the team needs to be fully determined and they can try to get at least a win in these 4 encounters. In the match against Psg, they can spoil the celebrations by defeating PSG and either Brest and that will see Lyon being placed in good position on the standings.
Lyon will be using it’s home advantage against Brest as that seems to be what could work for Lyon in this their match. A full dedication will help this Lyon team be able to overcome their obstacle and I think that is what could play out nevertheless the team must still be commended for how hard they’ve been able to fight to get to this spot on the log.
