Glasgow must do whatever it takes to reach RaboDirect Pro12 play-offs, says Sean Lineen Collectively, we've worked massively hard all year to give ourselves this opportunity. It's about everyone concerned bringing the same intensity, accuracy and spirit they have done throughout the campaign and making sure we earn the right to prolong our season. DTH van der Merwe makes his first start of the season after marking his comeback from shoulder surgery with the winning try off the bench in Treviso last month. Lineen said: "We're delighted to be in a position to give DTH a start. He underlined his class and game-changing ability against Treviso, and he's desperate to get back out there in front of the Warriors crowd and show them what they've been missing. Also coming into the backline are scrum-half Henry Pyrgos and winger Federico Aramburu, who captains the team with Al Kellock among the substitutes. Jon Welsh, Dougie Hall and Moray Low come into the front row while Tom Ryder is also promoted. Lineen added: "Federico Aramburu is a worthy captain for the team. Because he hasn't always played and he's not necessarily got the highest profile, people outside the group perhaps underestimate what a key influence he is within the squad. Every single player here holds him in great esteem for what he's achieved in the game and how he conducts himself. The bench is the strongest I've ever named as head coach of Glasgow Warriors, and I'm expecting them all to have a part to play in helping us land the right result. Lineen is moving to a Scottish Rugby Union recruitment role in the summer but he will keep emotion out of his and defence coach Gary Mercer's Firhill farewell. Lineen said: "It's great for myself and Gary and this group of players to have the chance to show our appreciation for the fantastic backing the Firhill crowd have given us down the years. The best way to do that is by winning the game and giving them a semi-final to look forward to, so we're taking sentiment out of it and keeping our minds on that specific task. I'm looking forward to seeing Firhill absolutely buzzing one last time. Chris Paterson looks to go out on a high Chris Paterson will grace Murrayfield for the final time as a player on Saturday as the retiring former Scotland international features in Edinburgh's final match of the season. The 34 year-old, who has a record 109 caps and 809 points for Scotland, will start at full-back in Edinburgh's RaboDirect PRO12 clash with Treviso. Paterson, who is set to take up a new non-playing role with Edinburgh and the Scottish Rugby Union, is one of six players named in the squad who will play their last game for Edinburgh, but scrum-half Mike Blair misses out in a playing farewell due to a shoulder injury. "I've always said that I want to go out playing the best rugby I possibly can and I'm ready to move on to an exciting future," Paterson said. My retirement is tinged with sadness but my overriding and lasting feelings are ones of happiness, enjoyment and fulfilment, having achieved far more than I ever thought I would and could have in 14 years of the job. I'm delighted to be involved in this game and, as always, have done my best in training and will do my best in the game. We've had a great season in Europe and have a chance on Saturday to remedy our league form and finish the season well, both for Edinburgh and me personally. Edinburgh lost their Heineken Cup semi-final to Ulster last Saturday and are to field a near full strength side. The other five departing players involved in the matchday squad have been named on the bench - replacement front-row forwards Andrew Kelly, Kyle Traynor and Jack Gilding, back-row Alan MacDonald and fly-half Phil Godman. Jim Thompson joins Blair in missing the farewell due to his participation in the Glasgow Sevens with Scotland.
