I assume the toughest game to predict on the final week will be
Forest - Chelsea.

Because both of them are still in the competition for a Champions League spot. Chelsea are one step ahead though.
I saw Chelsea being given over 2.00 odds for the win. Considering they also need to win, I think it could be given a chance. Forest are in worse shape recently. Chelsea should be better to handle this kind of critical moments.
Chelsea - Forest have to be the final match to get one UCL spot. I'll take safe bet for myself, which is btts. Not a fan to bet on one team, and seem both clubs to scores each other.
IMO, Chelsea a bit stronger than Forest considering how Forest has fallen. Blues can have greater chance as long as no more experiment come from Chelsea. 2.00 looks so damn big for Chelsea, but they obviously have greater chance here.
Still waiting for the official line up. Enough to use it as a way to determine the best bet to be taken.

That match is a must win for Chelsea else they should forget about qualifying for the next season's champions league once again, if Chelsea hasn't fallen apart this recent seasons, Nottingham Forest wouldn't have been a nightmare for Chelsea to win in that final day match. BTTS is a very good choice to bet because obviously, both teams will be considering a win in that game and they definitely will be hungry in scoring goals that will bring them the 3 points.
