I will bet over 2.5 on the match. I know crystal palace will get their win but not without Leicester city struggling to defend and making attempts as well. Getting a draw as well can be possible because Leicester are playing at home but it's risky as you said. The only player that might be worrisome in crystal palace is Wilfred Zaha and I doubt Leicester can defend well against him. If Leicester can limit Zaha's performance they will increase their chance of getting a draw
I don't know if this is a good bet, teams from the bottom of the table, it can be a cautious match, although you may be counting on Leicester's holey defense. In fact, both teams are very weak, but I think that Crystal Palace will not lose today, their defense looks much better. Even with Leicester playing at home, I don't see where they can have an advantage today. Everton are in good shape now, maybe they can give Tottenham a bit of trouble today and take points, what do you think?
