Ireland second-row Paul O'Connell is hopeful of securing a spot on the British & Irish Lions tour to New Zealand when his side take on England on Sunday.
O'Connell has been tipped as a Test certainty against the All Blacks this summer and has even been touted as captaincy material, although Ireland team-mate Brian O'Driscoll seems a more likely candidate.
O'Connell is convinced that a big game against England locks Danny Grewcock and Ben Kay would make him Sir Clive Woodward's first choice in the position, providing the outstanding Munster forward with a massive incentive at Lansdowne Road.
"Danny Grewcock has three caps for the Lions and has many more for England. Ben Kay is a big-game player and has done it time and again for Leicester.
"They're both setting the standard at the moment," he said.
"If Malcolm O'Kelly and I want to step up to the level these guys are at we need to perform against them.
"Games like this decide whether you make the Lions tour or not. You have to produce against these guys."
