It was a weekend where Welsh participation in the latter stages of either European competition was sparse, with the Ospreys the only club from this side of the bridge involved.

Unfortunately, Toby Booth's side couldn't quite overcome Gloucester at Kingsholm and must now turn their attention back to the United Rugby Championship, where they remain in contention for a play-off spot. But there were a handful of Welsh players who figured for English clubs in the last eight of the Investec Champions Cup.

There was also a full round of Welsh Premiership rugby to contend with. Here are our winners and losers from an entertaining weekend of rugby.

Winners

Dillon Lewis and Jarrod Evans

Both Wales internationals were second-half replacements during Harlequins' sensational 42-41 Champions Cup quarter-final victory over Bordeaux in France. This game will go down as one of the very finest in the 28 year history of the Champions Cup as Harlequins beat the odds to set up a mouth-watering semi-final clash with French giants Toulouse.

While Harlequins' attacking game has got all the attention, the difference between winning and losing was their set-piece dominance. Wales prop Lewis played his part in this coming off the bench to continue applying pressure on the Bordeaux scrum, winning a penalty in the process.

The 57 times capped international has improved his scrummaging since linking up with his former Cardiff coach Danny Wilson in south-west London. Former Cardiff outside-half Evans was a late replacement for England star Marcus Smith and will likely see more game time between now and the end of the season after recovering from a knee injury as he looks to force his way onto the plane for Wales' summer tour of Australia.

Whatever happens with international selection, both men will see a potential first appearance in a Champions Cup semi-final as big reward for taking the plunge and leaving Wales in the summer.

Morgan Morse

The 19-year-old came off the bench during the Ospreys' Challenge Cup quarter-final clash with Gloucester at Kingsholm and made a big impact. Morse isn't even 20 yet, but the backrower made some serious headway with some explosive carries while he put a big defensive shift in.

Unfortunately the Ospreys fell short of a first ever European semi-final place but Morse was a shinning light. The former Ysgol Gyfun Ystalyfera pupil is expected to figure for Wales U20s in the World Rugby U20 Championship in South Africa this summer but don't rule out Warren Gatland taking him to Australia with the senior squad instead.

Members of Warren Gatland's coaching team were in attendance on Friday night and could only have been mightily impressed with what they saw. It's a matter of when, not if, he plays for Wales at senior level.

Max Llewellyn

The 25-year-old was only on the field for 47 minutes of Gloucester's Challenge Cup quarter-final victory over the Ospreys but played well during that time. Llewellyn is a powerful carrier who more often than not gets over the gain-line while his distribution is very good.

The twice capped Wales centre is a very intelligent rugby player who makes good decisions both in attack and defence. Llewellyn didn't figure much for Gloucester at the start of the season but is enjoying a run of games and is playing well.

The former Cardiff midfielder was in direct competition with two other contenders for Wales' summer squad in Owen Watkin and the in-form Keiran Williams. Llewellyn more than held his own and is a serious contender to tour with Wales this summer.

Newport RFC

The Black & Ambers are enjoying a tremendous season and were mightily impressive on the weekend as they thrashed Bridgend 89-26 at home. Newport are top of the Premiership table for a reason, nine points clear of second placed Llandovery, and huge credit must go to head coach Tyron Morris.

Whoever plays Newport in the play-offs will have their hands full.

Losers

Ospreys discipline and set-piece

Under Toby Booth the Ospreys have always prided themselves on having a strong set-piece but this wasn't the case up at Kingsholm on Friday night. For some reason the Ospreys' lineout faltered, with experienced hooker Sam Parry responsible for a couple of throws which weren't straight early on.

While some refereeing decisions were a bit dubious to say the least, the scrum was also an area where they uncharacteristically struggled as Gloucester got on top. The Ospreys conceded 14 penalties, many of them under no pressure whatsoever, which killed any chance they had of building momentum.

Dafydd Jenkins and Christ Tshiunza

The Wales internationals were part of an Exeter Chiefs side which suffered a 64-26 thrashing at the hands of French Top 14 champions Toulouse in the quarter-finals of the Investec Champions Cup. Neither player played badly but they were part of a collective pack which got blown apart by the French giants in a ruthless second-half performance.

Exeter played well for the first 50 minutes, only trailing by a point at half-time, but capitulated thereafter. Both Jenkins and Tshiunza are very likely to be on Wales' summer tour of Australia so Gatland will be hoping for an improved performance from the two over the coming weeks.

Neath RFC

It's been a tough few months for Neath who are fighting for a place in next season's inaugural Elite Development Competition. The Welsh All Blacks are vying with Cardiff for the final place in the competition, having already been rejected once, but it is very likely they will miss out for a second time.

It was a difficult weekend for Neath in the Welsh Premiership as well as they 33-25 to Swansea at St Helens and they remain bottom of the table.
