Augsburg's South Korea forward Ji Dong-won is being lined up as an end of season target by his club's German rivals Borussia Dortmund, reports on Friday suggested.

Ji, 22, returned to Augsburg on Thursday for a second spell from Premier League side Sunderland.

According to the German media Ji will be offered a four year deal by last year's beaten Champions League finalists.

Ji, who has 26 international caps, was keen on a return to the Bundesliga to get some playing time in a bid to increase his chances of competing at the 2014 World Cup after appearing only five times since the start of the season for Sunderland.

Ji arrived at the Stadium of Light from K-League side Chunnam Dragons in June 2011.

He enjoyed a successful loan spell at Augsburg in the second half of last season, scoring five goals in 17 Bundesliga appearances.

He is due to have his first run out for Augsburg, ironically against Dortmund, on January 25.
