Top 10 summer deals
Ahead of the new Aviva Premiership season, skysports.com looks at 10 summer signings who could make a big impact at their new clubs.
The South Africa skipper might have been criticised of late over his form, but there is no doubting the class of the versatile front row. His arrival after the World Cup will be a vital boost for the Saracens as they look to defend their title, with a wealth of experience and a winning mentality. Smit and Schalk Brits together in the same squad is a scary prospect for oppositions.
Bath have fought long and hard to secure the capture of the All Blacks fly-half. With Butch James having left at the end of the season, the club were desperate to bring in a world-class No.10 - and despite his World Cup omission, Donald does fit the bill. The 28-year-old has polarised views in New Zealand for his international displays but he has been a consistent performer for the Chiefs and Waikato and Bath will be looking to him to pull the strings.
This could well be the make-or-break season for the enigmatic Tait. There is no doubting his ability, however he has struggled to make an impact in recent years. Injuries and a struggle to pin down a settled position have certainly hampered his progress but a move to Welford Road could breathe life into his career. A talented broken field runner, Tait has the ability to spot a gap and the pace to burn.
The vastly experienced lock arrives at Wasps after spells with the Crusaders and Bayonne. The 32-year-old, who was capped five times, will add dynamism to the Wasps pack while still being hugely effective in the set-piece. Wasps will also look to Filipo to help bring on rising star Joe Launchbury, with the young lock having been the player of the tournament at the Junior World Championships.
Northampton's pack has become one of the most feared in Europe over the course of the past few years - with the signing of Paul Doran-Jones only going strengthen their options further. Doran-Jones has made the switch from Gloucester and will be looking to make an immediate impact after missing out on England's World Cup squad. His ability to play on either side of the scrum will be key.
The signing of the Scotland centre is a massive coup for the Exiles. Ansbro had gone on to make the Northampton No.13 shirt his own in recent seasons, with his form earning him a call up to the international set-up and a place on the plane to the World Cup. The 25-year-old from Glasgow is a quick, powerful runner and his partnership with fellow new-boy Shontayne Hape could be key to Irish hopes.
It might have been a season to forget for Leeds, but not for Fourie. The South Africa-born flanker only enhanced his reputation with his phenomenal work at the breakdown, earning his place in the England set-up for the autumn internationals in 2010. He can count himself unlucky not to be on the plane for New Zealand, with Sale now hoping to reap the benefits.
Another player who can count himself unlucky to miss out on the England squad for the World Cup, with an unfortunate injury playing for the Saxons ending his hopes. Attwood, though, has had the time to settle into life at the Rec, with the second row the perfect replacement for Danny Grewcock. Very much in the mould of Martin Johnson, Attwood will add physicality to the Bath pack.
The scrum-half returns to England from Brive to be reunited with his mentor Richard Hill. Under Hill's guidance at Bristol, Perry became one of the top No.9s in the country, winning 14 caps and playing at the 2007 World Cup. Perry's experience and enthusiasm will keep the Warriors pack on their toes, while his link-up with former Brive team-mate Andy Goode will get the backs moving.
While the 26-year-old centre may not be well known outside the Championship, that could all be about to change. Hooper was one of the stars last season as the Cornish Pirates reached the play-off final, with series of eye-catching displays. Hooper, who has previously played in Australia for Manly and at Plymouth Albion, has the ability create space for others by off-loading in the tackle, while he is fearsome in defence.
