Jones hails improved Lions

British and Irish Lions captain Alun Wyn Jones knows there's still work to be done despite beating the Crusaders 12-3 on Saturday.

Following a shock defeat to the Blues at Eden Park on Wednesday, the Lions knew they had to strike back in Christchurch and certainly did that as they shut down the Super Rugby leaders in a disciplined performance that brought to an end the franchise's unbeaten run in 2017.

After the game Jones was pleased with his side's showing but also admits they still need to take their chances when they come in matches.

"We had quite a few line breaks that we didn't finish off again which is something we'll have to continue to work on. We had to match them at set-piece time and did that and that gave a platform for the backs and we made a few dents but didn't capitalise on them," he told Sky.

"The 23 stood up today and we needed that. There are bits of the set-piece to work on but it is an improvement again from the last game."

Emotionally the Lions looked super charged at AMI Stadium and while Jones agreed they were he also praised the calmness of the playmakers.

"We try to encapsulate that (emotion) in all of the performances but credit to 9 and 10 who steered us in the right direction," the second-row continued. "You can have all the emotion in the world but you have got to channel it the right way and we did that in parts tonight."
