Young front-rowers Harry Thacker, Riccardo Brugnara and Tiziano Pasquali have all committed their futures to Leicester Tigers after agreeing new contract terms.Following in the footsteps of senior front row colleagues Marcos Ayerza, Tom Youngs, Dan Cole and Fraser Balmain, the trio have all extended their stay with the club beyond the end of this season.   Leicester-born hooker Thacker, 20, has already picked up a Goldsmiths Player of the Month award this season with some impressive form in the senior squad, while props Brugnara and Pasquali have also gained first-team experience in league and cup.   Tigers director of rugby Richard Cockerill, announcing that agreement had been reached with all three players, said: “Harry, Riccardo and Tiziano have all come through our academy teams and the development squad to earn a place in the senior set-up and are learning their treade in very good company.   “We have a very good crop of front rows led by international players Marcos Ayerza, Tom Youngs, Dan Cole and Logovi’i Mulipola, plus Michele Rizzo and Leonardo Ghiraldini who have joined the club this season and Fraser Balmain who has come through the ranks here in the last few seasons.   “They are all good players and I hope we can keep that group working together over the next few seasons.”   Thacker is a member of the England Under-20s squad and has scored three tries in four senior appearances for Tigers, as well as claiming a hat-trick on Premiership ‘A’ League duty this season.   Italian-born duo Brugnara (21) and Pasquali (20) were part of the Tigers development squad last season before stepping up to the senior squad for 2014/15.
