Marcos Ayerza says he is "proud to be part of the Leicester family" as he prepares for an historic showpiece fixture between club and country at Welford Road next Saturday.Argentina head coach Daniel Hourcade brings Los Pumas, in their final run-out before opening their Rugby World Cup against the All Blacks, to Welford Road to face Leicester Tigers in the Marcos Ayerza Testimonial Challenge.   Ayerza joined Tigers in 2006 and has now topped 200 club appearances - as well as picking up the Supporters' Player of the Year award in 2014/15 - and passed the 50-cap mark for the Pumas.   “After almost 10 years I feel this is my club and my place,” said Ayerza. “I am proud and happy to be part of the Leicester family.”   The Pumas are in a World Cup pool with New Zealand, Tonga, Georgia and Namibia, and coach Hourcade hopes they can win new support at Welford Road as the city hosts two of their pool matches.   Their 31-man squad includes Ayerza and former Tigers favourites Horacio Agulla, Lucas Amorosino and Pablo Matera as well as Marcelo Bosch of Saracens, skipper Agustín Creevy, back-rower Juan Martín Fernández Lobbe, fly-half Juan Martín Hernández and wing Juan Imhoff who made history with a hat-trick of tries in this summer’s historic win over South Africa in Durban.   The return of international opposition also signifies the first match of 2015/16 for Tigers, with a chance for a number of summer signings to experience a Welford Road matchday for the first time.   Kick-off next Saturday is at 3pm.   Tickets are available now, priced £25 adult seating, £10 junior or £60 family (2 adults, 2 juniors), or £22/£8/£52 terrace.   Purchase in person at the Tigers Club Store at Welford Road (9am-5pm weekdays and 9am-5pm Saturday) or phone 0116 319 8888 (option 2) (8.30am-5pm weekdays and 9am-5pm Saturday).
