Levante has been favored on the moneyline three times this season, and has finished 2-0-1 in those games. Real Oviedo has been an underdog in 26 games this season, and won four (15.4%).
Real Madrid has won 20 of its 27 games when listed as a moneyline favorite this season (74.1%). Elche CF has won one, or 4.8%, of the 21 games it has played as an underdog this season. Real Madrid has gone 10-0-1 when playing as a moneyline favorite with odds of -306 or shorter (90.9%).
I fancy Chelsea. I think it could be 0-0. I think it will be a draw or a Chelsea win. Arsenal only won the second leg of the Carabao Cup semi-final because Chelsea needed a goal late on and it opened up.
