Was tempted to bet on the Man Utd match but i think they could slip up after their mid week Europa League game. Similarly, i think Ajax will not perform at their best tonight against Heracles.
Heracles are probably the antithesis of Dutch football. Defensive and low-scoring, i think they could frustrate Ajax tonight. Last season, they won this fixture and with Ajax thinking about European football, now's the perfect time to play them.
So between a +1.5 and a +2 handicap, i'm going to bank on their defence not conceding 3 goals against Ajax. Also, Ajax only win 60% of their away matches so +2 @1.55 looks like a decent punt.
