The Premiership's Top 15 GREATEST imports featuring Ayerza, Brits, and Evans

How immeasurably more boring would our sporting lives would have been.

So, in the past 20 years, who have been the best 15 overseas signings to grace this country’s pitches? RUCK gives it a go:

No player was able to make such an impact in such a short space of time. Moving to Wasps ahead of the the 2015-16 season, Smith won a number of awards; including Wasps' Players' Player of the Year, Wasps' Player of the Year, Aviva Premiership Players' Player of the Year and Green Flag Forward of the Season. During his spell in England, Smith was also involved in the England coaching setup during the 2016 Six Nations Championship. He's now back in the Premiership with Bristol Bears.

The legendary Springbok captain, who famously won the Rugby World Cup on home soil in 1995, made the move to Saracens in 1997. Under his leadership, they defeated the London Wasps to win the Pilkington Cup and also finished second in the Zurich Premiership. During the next two seasons, they secured third and fourth spots in the Zurich Premiership, thereby qualifying for the European Cup on consecutive campaigns.

The Wallabies legend joined Newcastle Falcons in 2004 after retiring from international rugby. Here he has played alongside former English rival Jonny Wilkinson (his opposite kicker in Lions tour of Australia). He has also won the 'Player of the Year' at the Falcons and was named as captain of the side. Rediscovering his best form, the Wallabies wanted to recall Burke, but he rejected this, citing his commitments Newcastle.

An undisputed fans’ favourite, Reihana pulled on the black, green and gold 236 times in a nine-year career at the Saints, becoming only the fifth player to score over 1,000 points for the club in the process. An All Black upon joining the club in 2002, it was the full back’s exciting style with ball in hand and charismatic grin off the field that endeared him to the Saints faithful. Captain for three seasons, Reihana lifted the Challenge Cup in 2009 following a National One and National Trophy double in 2008, while he was also part of the squad that won the LV= Cup in 2010 and reached the 2011 Heineken Cup final.

In his first season at Newcastle, he made 22 appearances as they won the 1997-98 Premiership. However, after that triumph he moved on to Northampton Saints, with whom he won the 1999–2000 Heineken Cup Lam moved back to Newcastle Falcons for the 2001–02 season, playing with the club for a year before retiring.

Rejecting the opportunity to be Dan Carter's understudy, Evans made the brave move to the Premiership with Harlequins after the 2007 Rugby World Cup. Nine years on he hung up his boots as one of the clubs greatest ever players, scoring 2,249 points in 208 matches. A standout moment was probably his 20-point haul at Twickenham as Harlequins won their first ever Premiership title against Leicester in 2012.

The winger qualifies for this select group via his Samoan heritage. He also played more Tests for Samoa than he did for New Zealand but, above all else, taught everyone at Wigan and Newcastle Falcons what class looked like regardless of the code he was playing. He's still talked about two decades on from Newcastle’s title-winning heyday.

The USA international joined Northampton in 2011 and hit the ground running with a series of powerful performances in the early rounds of Aviva Premiership. Named by ESPN to the 2011-12 Premiershp "Dream Team.", the back-rower signed a three-year extension and won the Northampton Saints Supporters' Player of the Year for the 2012-13 Premiership season.

After lifting the European Rugby Champions Cup twice and the Premiership trophy on three occasions during his seven seasons with Saracens, du Plessis is now with London Irish. A stalwart of the Premiership, he's been one of the most consistent performers the division has ever seen, making 100 appearances for Sarries.

Joining Leicester in 2005, he made an immediate impact in English rugby's top flight and was named Guinness Premiership Player of the Year at the end of his debut season - in the process becoming the first prop and Italian to scoop the honour.  He acquired cult status at Welford Road and a reputation as one of the league's most fearsome props. Castrogiovanni played a key role in the Tigers' dominance of the England domestic scene in the naughties helping them to Premiership titles in 2007, 2009 and 2010.

The hard-as-nails former Namibian skipper helped Saracens become the most feared defensive unit in Europe. When you consider he also overcame knee surgery that would have made a rhino wince, his strength of character was almost superhuman. For his performance in Saracens’ famous 46-6 win over Clermont in a European semi-final alone, he deserves his place in the top five on this roll of honour.

Murphy, who made his Tigers debut in 1997, played in seven Premiership-winning teams and won two Heineken Cup finals. The fullback was one of the most outstanding players in the history of Premiership rugby. He won 72 caps for Ireland, two Test caps for the Lions and has scored 691 points, including 93 tries, in Leicester colours.

Warren Gatland rated Leota as the best hooker in the world on his day. The powerhouse

The enigmatic prop is one of the greatest players in Leicester Tigers history and proved the catalyst for their Premiership dominance. The Argentine, despite being an established international, signed his first-ever professional contract with Tigers, but few would have imagined he'd be a stalwart at the club for over a decade, making 246 appearances and winning four Premiership titles.

When he retires at the end of this season, Schalk Brits deserves to be acclaimed as the greatest import in the history of the Premiership. He is that good. Joining the club in 2009, the South African hooker has helped to redefine the role of the hooker with his pragmatic style of play, making over 200 appearances for the club, winning a heap of trophies.
