Treadwell, who joined Ulster in 2016 from Harlequins, will return to his former side at the end of the season.

And the 29-year-old wants to savour his last few games in an Ulster jersey and inspire the province to a strong end to the season.

“You soak everything in, after Bordeaux I was like ‘wow this is my last European game for Ulster,'” he told BBC Sport NI.

“I’m soaking up everything; the environment, the boys, the wins, the losses and the work we’re doing on the training pitch.”

Treadwell said that the mood in camp is “good” despite their 43-31 defeat against Bordeaux in the last-16 stage of the Investec Champions Cup last time out.

“We still have disappointment from Bordeaux, we felt like we actually could have put a few more shots together and scored a few more tries,” he added.

“I think we are going in the right direction, stringing some good play together, and defensively we are making strides, so hopefully that can snowball into this week.”

They face another tough assessment in the United Rugby Championship on Saturday as they face Leinster at the Aviva Stadium, but Treadwell, who starts the game on the bench, believes his side should look forward to the challenge.

“It’s a different challenge and they pose different threats, but it is going to be a massive game, these games leading in are really important as the table is really tight and it’s effectively play-off rugby now,” he continued.

“I’d say they’re one of the best, but most of the focus this week is going to be on us and how we can learn from Bordeaux.

“It’s an occasion in a massive stadium and something we can be excited for but that we can’t let get the better of us.”
