Chelsea are very close to achieving Champions League qualification. They need to win their next game against Nottingham Forest because it might be a deciding game for the Champions League qualification campaign, it will be a really difficult game because Nottingham Forest are also in the race for the top 5.
Nottingham forest are currently in the 7th position in the Premier league table, they are not too far from getting into the top 5 but I honestly do not think they can achieve it, Chelsea will do everything they can to either remain in their current position or climb higher, so like you said, it's going to be a very tough match, but I personally see chelsea beating Nottingham forest.
And away from that, let me use to medium to also congratulate Arsenal for beating Newcastle yesterday by 1 goal, this turned out to be a tiny space for escape for Arsenal, I never expected them to win that game but behold, they won, I hope they will fight harder to ensure they win all the coming games from now on, so they could keep maintaining their 2nd position in the league table until this season is over and done with.
