Manchester United and Arsenal are both reportedly interested in signing Hertha Berlin teenager Arnie Maier.

Maier, 19, has played every minute of Hertha Berlin's 2018-19 Bundesliga campaign to date.

The midfielder is a Germany Under-21 international, and came through the youth system at his current club before progressing to the first team.

According to The Sun, both United and Arsenal have been watching Maier this season, and the pair are expected to go head-to-head for a player who could cost in the region of £30m.

Maier has a contract with Hertha Berlin until the end of the 2021-22 campaign.
