Five things we learned from Challenge Cup last 16

Guess who's back, back again, Farrell's back...

Owen Farrell returned from groin surgery to score five points against Perpignan as his Racing 92 gained some much-needed positivity by booking their place in the quarter-finals.

The Parisians languish down in 11th in the Top 14 and under serious threat of relegation but the former England captain's return could prove timely, especially with a visit of Connacht to come in the quarter-finals.

Cherry and White delight in Montpellier

Gloucester provided the Premiership with a rare boost last weekend when they downed Montpellier in the south of France.

Freddie Thomas, Cameron Jordan and Ruan Ackermann crossed for tries as the visitors fought back from a 14-0 early deficit to maintain last season's finalists aspirations of securing a third title.

Bath continue bid for treble

Tyro 10 Ciaran Donoghue guided the Premiershop table toppers into the last eight with a faultless 14 points off the tee in their dominant victory in Pau.

Bath had to overcome Sam Underhill's second-half red card but the result was never in doubt for the Premiership Cup winners, who outscored their hosts seven tries to three.

Ospreys fly the Welsh flag

Ospreys exacted revenge on their bitter rivals, the Scarlets, to book a quarter-final match at home to Lyon on Saturday.

With half-backs Reuben-Morgan Williams and Dan Edwards orchestrating matters, tries from Adam Beard, Jac Morgan, Rhys Davies, Dewi Lake, Jack Walsh and Daniel Kasende overwhelmed Scarlets in this all-Welsh knockout affair.

Bulls become SA's only Euro hope

The Bulls were victorious in Bayonne, overcoming a hostile crowd to march into the quarter-finals as the sole South African representatives in either EPCR tournament.

Fly-half Keagan Johannes kicked seven points in the triumph, while their fellow countrymen, the Sharks, were beaten on Sunday in Lyon.
