Scarlets, who reached the semi-finals of the European Rugby Champions Cup last season for the first time since 2007, have strengthened their squad with a mixture of Welsh and southern hemisphere talent in a bid to go a step further this season. Here we look at some of their summer signings. Kieron Fonotia The 30-year-old New Zealand-born utility back has joined Scarlets from Welsh rivals Ospreys after two seasons with the Swansea-based side, for whom Fonotia made 10 European appearances and scored three tries. The Samoa centre or wing moved to Wales in 2016 from Crusaders after three years with the New Zealand Super Rugby team. https://twitter.com/scarlets_rugby/status/1019900658424713217 Blade Thomson The versatile forward, who can play in the second or back row, is reunited with Hadleigh Parkes at Scarlets, with the pair having played together at New Zealand Super Rugby side Hurricanes. Thomson, 27, a Junior World Championship winner with the All Blacks in 2010, made his Super Rugby debut in 2013 and played over 40 games for Hurricanes. Uzair Cassiem Cassiem has Test, Super Rugby and PRO14 experience, having played for South Africa eight times and the Cheetahs in both the latter two competitions. The 28-year-old former Golden Lions, Falcons and Pumas forward, who began his senior career in 2011, can play anywhere across the back row. https://twitter.com/scarlets_rugby/status/1019589746589302786 Clayton Blommetjies Like Cassiem, Blommetjies has joined Scarlets from the South African PRO14 Cheetahs side, where he played 90 games in four years after a similar period with Blue Bulls. The 27-year-old, who represented South African at student and U20 levels, can play at full-back or on the wing, and head coach Wayne Pivac has earmarked Blommetjies' flexibility for offering Scarlets options during the international windows. Sam Hidalgo-Clyne The signing of Hidalgo-Clyne gives the Scarlets another goal-kicking option, as he amassed 192 points in only 26 Challenge Cup appearances for Edinburgh Rugby. The 24-year-old Scotland scrum-half helped Edinburgh reach the final of the 2015 Challenge Cup in his maiden European season with 99 points in just nine games. Angus O'Brien O'Brien is also a useful goal-kicker, having chalked up 80 points in 18 Challenge Cup appearances for the Dragons before his departure from the Newport-based region at the end of last season. The 23-year-old fly-half previously played for Welsh Premiership club Cross Keys and is a former Wales U20 international.
