Form guide
Rennes lost 4-0 at Lyon, beat Auxerre 4-1, lost 4-3 at Paris FC, beat Strasbourg 3-0 and lost 5-2 at Nice.
Olympiacos won 1-0 at Levadiakos, beat Panathinaikos 1-0, won 2-0 at Panetolikos, beat Kalamata 5-0 and won 3-2 at Kifisia.
Our prediction and why
We take Over 2.5 goals. Rennes scored three or more in three of their last five and Olympiacos scored in all five, which fits our rule. Every one of Rennes' last five league games had three or more goals. Olympiacos' tight wins are why we rate it lower than our other picks.
