Aaron Anselmino hailed as 'world-class' after impressing Borussia Dortmund coach in first game after transfer from Chelsea

Anselmino, who arrived from Chelsea as a loanee last week, started for Dortmund against Union Berlin and marshalled the backline to help his team earn a 3-0 win, their first of the Bundesliga season.

The 20-year-old Argentinian joined Chelsea last summer from Boca Juniors and arrived in London earlier this year after being loaned back to the Argentine club. His only appearance for the Blues has been a two-minute cameo against Benfica in the Club World Cup and first-team opportunities were expected to be limited this season. With Dortmund running short of defenders in their squad, a temporary switch to the Bundesliga was arranged. 

He slotted straight into the starting XI against Union Berlin days after his arrival in Germany and impressed the Dortmund boss. Moreover, he also set up Serhou Guirassy for his team's second goal before he went off with cramp after 75 minutes.

Kovac said after the game to DAZN: "Anselmino played a world-class game. That's why we brought him in. He's physically fit. He lacks rhythm. When you haven't played for a long time, you get cramps like that. But Aaron is physically in top shape."

Dortmund will resume their Bundesliga action after the international break on September 13 to face Heidenheim.
