They opened the season with an 18-13 triumph over Benetton Treviso and it is the Italians who are their first opponents as they begin their European campaign on Saturday night.
That clash will take place at Thomond Park and Foley is fully aware of the importance of home form if his troops are to challenge at Europe's top table this year.
"It doesn't matter what competition you enter, it's all about momentum," said Foley.
"You often hear it around Six Nations, World Cups, GUINNESS PRO12, everybody's looking for momentum to get into the competition. We're no different.
"We're fortunate we've got our first game at home and historically, you look at the home games in Europe across every team and every team at home wants to win their first game.
"We're steadily on an upward curve and in a good position going into Europe. It's about us now getting our performance right against Treviso which is going to be a very tricky fixture."
