I don't suggest handicap fpr Real Madrid, especially against Shakhtar Donetsk. Yeah they can win but Shakhtar Donetsk is a tough team with their wolf coach Lucescu.
Real madrid is still real madrid , they will win this by more than 2 goals so -1 for them is a good bet. Shaktar is a good team but still you cant compete them with real madrid, they are in very different level there
Agreed with you Real Madrid will win for sure and maybe 3-0 that is most possible chance for this match over 2.5 goals is good choice to bet on this match.
