We used the 3 main prediction models to find the validity of a gg in this Chelsea vs Crystal Palace match. The Monte Carlo simulation prediction model indicated a 55.69% probability for a GG outcome. 

The ELO Ratings model came through with a 58.43% probability for the same outccome. The third model, Poisson probabilites prediction model showed there's a 60.18% chance for a gg outcome. This Chelsea vs Crystal Palace match has a few other bets that have been validated by all the 3 models. 

Keep reading to find them all. To find if the Gg bet is a value bet, we need to compare the implied GG bookmaker probability with calculated and validated Surebet probability for the same. The odds for this outcome are averagely 2.41 with an implied bookmaker probability of 41.49%. 

The calculated Surebet probability for the Gg outcome for this Chelsea vs Crystal Palace match is 58.10%, meaning this bet is a value bet. In case you place this bet, you may gain expected value by 16.60%Expected Value, EV(GG), for a GG result for this Chelsea vs Crystal Palace match is calculated as follows: Let P(GG) be the probability of winning this bet, P(0) be the probability of losing this bet. 

Also assuming that your stake is 100 then the Expected value is; P(GG) * 100* 2.41 where 2.41 are the decimal odds for this outcome. Using this formula then you should get the expected value for a GG for Chelsea vs Crystal Palace, EV(GG) to be 58.10% * 100 * 2.41, which translates to 98.11. This is a positive Expected Value thus further vaidating this bet mathematically.

Historical data, H2H matches and results from similar and related past matches, Surebet GG prediction systems have all agreed that both teams will be able to score in this match. Both Chelsea and Crystal Palace have good striking and have equally vulnerable defenses. 

I do not forsee a NG outcome for this game. The GG rediction for this game is both teams to score at leat one goal in this game.
