Good afternoon and welcome to Ultimate Rugby's live European Challenge Cup coverage. Gloucester get their title defense underway with a home fixture with Zebre. The aim for Gloucester is securing a home quarter final and a winning start today is crucial. Despite recording some impressive victories in the Pro 12 a win on the road today looks a massive ask for Zebre. Follow all the action here with kick off coming in 15 minutes time.

Can we have match day squads posted please Ultimate Rugby.

Gloucester won all 9 of their games in last year's competition on their way to lifting the trophy & a win over Zebre would set a club record for most consecutive wins in the competition.

No Italian clubs have defeated any English opposition in the tournament since December 2007.
