Manuel Neuer has beaten off competition from Marc-Andre ter Stegen for Germany's number one shirt, but an uncharacteristic error from the veteran put the hosts on the back foot in the first half, Giorgos Masouras finishing when the goalkeeper failed to hold Christos Tzolis' shot.

Kai Havertz had a goal disallowed for offside shortly before half-time, but he would not be denied after the break as he saw a shot deflect in after being fed by Leroy Sane.

Substitute Benjamin Henrichs rattled the crossbar from distance with 84 minutes gone as Germany's bid for a winner looked like falling flat.

However, Brighton and Hove Albion man Gross gave the home fans something to cheer with one minute of the 90 remaining, firing a half-cleared cross into the top-right corner for his first international goal.

Germany fired off 27 shots without finding the breakthrough against Ukraine in a goalless draw, but it was a very different game against Greece as it rode its luck somewhat.

Julian Nagelsmann's team recorded just 12 shots worth 0.88 expected goals (xG) to Greece's 14 (2.14 xG), with a brilliant finish from Gross bailing it out after the visitor failed to take its chances.
