O'Brien and Van der Flier boost Blues
Wasps v Leinster, Champions Cup Pool One: Ricoh Arena, Sunday, 3.15pm
The weekly fight for spots in the starting Leinster back-row is a microcosm of the battle for places in Joe Schmidt's World Cup squad and the return of Seán O'Brien to full training this week has only heightened the competition.
At openside, Josh van der Flier is the man in position for club and country right now and he is likely to get the No 7 jersey for the Six Nations opener against England having starred in the win over New Zealand in November.
Last weekend, he impressed against Toulouse and displayed an increasingly strong poaching game that saw him come up with a big first-half turnover when the game was in the melting pot.
When he broke on to the scene, Van der Flier was renowned for his carrying and tackling but he is developing his breakdown work with help from Leinster's contact coach Hugh Hogan in the knowledge that the more strings he has to his bow the better when it comes to the big selection decisions.
"I was happy enough with that," he said of the penalty against Toulouse.
"Whatever way the lad fell right at my feet, it's one of those when you go in for a poach and the ball just kinda pops up in your hand so I was happy with that one.
"It's something I try to work on a bit, especially with Hugh Hogan each week. It's something Stuart (Lancaster) has talked to me about, he played No 7 as well.
"Sometimes I'd think I need to be getting loads of turnovers every game, but he said you have to be smart about it.
"If I go in for a ruck to try and get a turnover, then there's one less man in a defensive line, so I could be messing things up for the rest of the team-mates.
"So it's something to be smart about and when there's opportunities there, try and take them, but it's something I can constantly work on."
Van der Flier is acutely aware of the pressure for places.
"It is always incredibly competitive," he said. "You have Dan (Leavy) and Seán O'Brien and Scott Penny now doing incredible as well so there is an awful lot of competition.
"You just try to focus on your own game and play as well as you can. You can't be lazy or complacent."
Those are not words you would associate with the 25-year-old.
