Leinster

Before Ireland’s Six Nations win over Scotland in March, which secured the triple Crown, Farrell said he expected both Lowe and centre Bundee Aki to sign new contracts.

Aki has agreed a new one-year deal to stay with Connacht but there has not been any progress with Lowe, who is contracted by Leinster rather than an central contract with the Irish Rugby Football Union [IRFU].

Lowe did not make the squad for the Champions Cup final defeat by Bordeaux despite having returned from a hamstring injury sustained in the Six Nations win over England.

However, his two record-breaking tries on Saturday show he is still a threat when fit and available.

While Cullen declined to comment on his future, he did praise the impact Lowe has made since he moved to Ireland nine years ago.

“He’s been a great character in the group. Very, very different, you know, what he brings, great energy,” Cullen said after the game.

“Internally, we had a video there just in terms of some of the stuff that he’s done in a Leinster jersey over his career.

“There’s not many James Lowes running around the streets that we’ve come across so far. He’s been a great addition to the group over the years.”

Cullen and Leinster, who had comfortably cruised through the tournament last season, came under intense scrutiny after Northampton’s fast start saw them take a 12-point lead at half-time.

The four-time champions fought back and almost snatched the game at the death, with Cullen revisiting late refereeing decisions that cost his side in the 37-34 defeat last May.

A year on, he defended his side, who had previously never beaten three-time champions Toulon, and said he always expects a Champions Cup semi-final to “never go to script”.

“Naturally [in the last 10 minutes] you try and protect things, don’t you? Whereas the other team they don’t have protection and throw everything at it,” he added.

“We were sitting in this room this time last year. We were in that situation and we were throwing everything at Northampton. [Henry] Pollock gets a poach – it should have been a penalty.

“It’s clearly illegal, but nobody wants to report about it after. We should have had a penalty try and nobody wants to report about it. You just want to kick the boot into us, don’t you? But that’s the way it goes.

“Semi-finals come down to the tightest of margins. In 2012, Wesley Fofana knocked the ball over the tryline and that is how we [Leinster] got to the final.

“I would be kind to Toulon as they showed great spirit to the very end.”

Leinster will travel to Bilbao for the final on Saturday, 23 May, where they will face last year’s champions Bordeaux-Begles or Bath, who play on Sunday.

Cullen confirmed centre Robbie Henshaw and flanker Josh van der Flier, who left the field with head injuries, will undergo the graduated return-to-play protocol.

Flanker Jack Conan limped off and “will get checked”, with Tommy O’Brien said to be likely suffering from cramp.

All four are important players for Cullen as Leinster seek a fifth Champions Cup in three weeks’ time.
