"This game will be won or lost up front. Ulster have been heavily reliant on their pack this year and they have used it really effectively to win games.
The being said Connacht are known for throwing the ball around. They have Bundee Aki and Mack Hansen – there’s a plethora of guys who can do some damage in that backline."

The last time Ulster won a trophy, having a few fried onions on your pre-match hotdog or burger may have been as close to gourmet as you could get at their Belfast home.
Now, of course, 17 years on from the province's league title success, the array of eateries at Kingspan Stadium makes for an inviting aroma around the ground.
Will Dan McFarland's men be tasting trophy success this season, though?

The early May sunshine has just gone down in this part of Belfast as the players from both sides go through their warm-ups.
Time to get the game heads on - and you can feel the excitement building among the gathering crowd.
