Ulster captain Rory Best believes the club's fans can give his side the edge over Scarlets in the Heineken Cup Pool Four clash at Ravenhill tonight.
Ulster go in search of their first points in the competition this season and realistically have to win all their remaining group games to progress to the knock-out stages.
Best said: "It is an old saying and a bit of a cliche but it is true - our supporters really are the 16th man and they really do help us.
"It says a lot about our supporters that they have stuck by us week in, week out over the last year when things haven't been going so well, it really means a lot to us that they do stick by us.
"It drives us on and we feel now that we can give them some good rugby to watch, we are improving and we want them to see that, we want to give them more to cheer about and to support.
"I know there isn't much spare cash about at the minute and people are finding it tough, so I just want to encourage our supporters to come along to Ravenhill to watch Ulster play and I hope that they will go home happy and feeling proud of their province and their team."
