Paul O'Connell has thrown his name right back into contention to be included in Warren Gatland's British and Irish Lions squad for the summer tour of Australia, with increasing calls for the Munster star to be named captain.
O'Connell put in a man-of-the-match performance as he inspired Rob Penny's men to a shock 18-12 quarter-final victory over reigning Aviva Premiership champions Harlequins on Sunday, proving a colossus at the Twickenham Stoop.
It's been described as one of the second row's best-ever performances as he embodied Munster's intensity and ruthlessness, shining in the lineout as Quins wilted.
The second row's display was made all the more remarkable by his return from a back operation just two weeks earlier, churning out a quietly impressive performance against Connacht which indicated he would be ready for the European tie.
O'Connell, who captained the side which lost to South Africa in the 2009 series, has been plagued with injuries over the past 12 months with fears over his long-term future in the sport, but O'Connell has put himself back in the mix for selection.
In the words of Quins director of rugby Conor O'Shea, O'Connell's performance was "majestic" and "magnificent" and British & Irish Lions head coach Warren Gatland admitted the second row was in his thoughts.
"The older players with a bit more experience have the upper hand because they have that behind them, don't they?" Gatland told the Irish Examiner.
"We know a lot about Paul O'Connell. We know what he brings to the party so we will be keeping a pretty close eye on him."
Not only has O'Connell inked his name onto Gatland's team sheet for the tour of Australia, but there is a renewed clamour for the 6ft 6ins Munster star to captain the Lions.
With Munster struggling for consistency throughout the season, O'Connell galvanised his team-mates through his leadership and leading by example as he showed a ruthless edge.
Like Brian O'Driscoll, O'Connell's inclusion would be a fitting last hurrah for the second row who has enjoyed a decorated career with Ireland, Munster - and even the Lions - and his experience would be a valuable commodity Down Under.
