Catalans get a penalty in centre-field, 20 out.

They're going for goal.

The scoreline probably doesn't reflect how good they've been because they've missed their conversions.

Dominant.

Morgan Knowles streaks through and Saints are almost to the line.

Catalans struggling to cope here...

Goodness knows what I put on the second try post that has prompted so many dislikes.

Unless it's been hijacked by Wiganers?

Anyway, Saints purring now. This is a test of Catalans mettle as we head toward half-time.

They had a brilliant 20 minutes but have been opened up since.

Lewis Dodd threads and chases his own grubber in behind after a flowing Saints move, and it's gone to James Child in the video ref's box.

Saints are stomping downfield now at every ruck, and that ruck-speed is really telling the pace for Catalans.

They've just got a penalty on the back of one such drive from Alex Walmsley.

Saints in roll-you-up mood at the moment.

That was Konrad Hurrell at his best. Destructive running, just chugging past people and over people.

Catalans are struggling to make their way out at present, despite bringing the bulk of Sam Kasiano onto the field.

That can put pressure on Lewis Dodd. I'm sure Doddy will start knocking them over, but he'll be asking his team to get them a little bit closer to the sticks so he can get his confidence up.

There were only two points between these two at Old Trafford last year, and just one-point between them at Magic Weekend.

You can see how keenly matched they are in this bruiser of an opener.

Sione Mata'utia started off as an outside back before stepping into the pack, so you'd like to think that bit of execution was muscle memory from him.

Joe Batchelor has just carved open a big gap in the Catalans defensive line, with a powerful surge.

Saints have the bit between their teeth now.

St Helens get to a kick deep in the Catalans half, but the little grubber is taken in.

Saints apply some squeeze and Mitchell Pearce's clearing kick is from his own 10.

Is the pendulum swinging the home side's way?

Saints finally get a kick away in a good area, Sam Tomkins allowing it to bounce, but Catalans pouch it.

Tom Davies then splits the line and hares away but Saints make a challenge.

The England winger then knocks on at the play-the-ball and Saints get the ball back.

Catalans last tackle play, a kick from Mitchell Pearce, put Saints back on their own line.

However, a couple of quick rucks from Tommy Makinson, Sione Mata'utia and Alex Walmsley get them some front-foot ball.

They've lacked it.

Something you don't see everyday. Saints ending their set on their own 30/40, and having to kick through Lewis Dodd on Catalans' terms.

We've waited since October for all this to return, and while it's not been the most expansive game so far, it's definitely been explosive.

Catalans are the side in the ascendancy, getting to their last tackle options, but this time Josh Drinkwater's kick is taken on the fly by Jack Welsby and Saints get a quick ruck.

Gil Dudson comes off the back fence with the return from the restart and Matty Lees comes shuttling through to smash him for Saints.

The next play sees the next carrier Samisoni Langi get similar treatment.

It's all going off again. Dylan Napa is involved. Mark Percival is in there.

It's properly ignited this. Grudge match fayre.
