Robert Lewandowski has made himself the "most complete striker in the world", according to former Borussia Dortmund team-mate Ilkay Gundogan.

The pair were together at Dortmund from 2011 until 2014, before Lewandowski hopped across Germany to join Bayern Munich.

Gundogan left BVB in 2016 for Manchester City, where he plays with Argentina striker Sergio Aguero and Brazil forward Gabriel Jesus.

But he has kept a close eye on Lewandowski's development and now sees the Poland international as being unparallelled in world football.

This season had seen 31-year-old Lewandowski score 25 goals in 23 Bundesliga appearances for Bayern, and 39 goals across all competitions, before the coronavirus pandemic hit Europe.

He was on his way back to fitness after a tibia fracture when the Bundesliga was put on hold.

"It was a huge joy to play with him. He improved again and again," Gundogan told DAZN.

"Technically he was always great, now he also has the coldness. The way he scored the goals is phenomenal.

"For me [he is] currently the best, most complete striker in the world."
