Winger joined French side a year ago but could end England exile if given Aviva Premiership chance
Chris Ashton has asked to leave Toulon after just 12 months in France and could be set for a return to England.
The winger broke the Top14 try-scoring record with 24 in his debut season with the three-time European champions, but under RFU rules is ineligible for selection by his country while playing his domestic rugby abroad.
Ashton, 31, reminded England head coach Eddie Jones of his talents with a hat-trick for the Barbarians at Twickenham on May 27, as his side ran out 63-45 winners.
Toulon finished fourth in Top14 last season, enough to qualify for the end-of-season play-offs where despite an Ashton try they were knocked out in the quarter-finals by Lyon after a 19-19 draw, by virtue of having scored fewer tries in the game.
The former Northampton and Saracens man was prolific for England, scoring 19 times in 39 tests, including a super try against Australia in 2010, but has not featured for his country since the 2014 New Zealand tour.
French outlet RMC reported on Wednesday night Ashton was looking to break the three-year contract he signed last summer, with a potential return to his homeland on the cards.
Ashton began his career in rugby league before crossing codes in 2007, leaving Wigan Warriors to join Northampton.
He was awarded Premiership Player of the Season in 2009/10 with the Saints before joining Saracens in 2012.
In his time there he won two Premiership titles and a European Cup, but his performances were not enough to break back into the England setup.
After missing out on the 2015 World Cup squad and Jones showing no signs of giving him a look-in, Ashton made his switch to France official in October 2016, before joining up with his new team the following summer.
