Bayern Munich 1-0 Union Berlin: Eric Dier makes debut for home side in narrow victory

Bayern Munich bounced back from Sunday's Bundesliga loss to Werder Bremen with a 1-0 win over Union Berlin at Allianz Arena.

Thomas Tuchel's side started the game seven points adrift of leaders Bayer Leverkusen and have used their game in hand to close that gap to four.

Raphael Guerreiro scored 30 seconds into the second half after Harry Kane hit the post.

England's Eric Dier came on at half-time for his Bayern debut.

The centre-back joined the German champions earlier this month on loan from Tottenham.

After a dull first half, the intensity was upped in the second period with Bayern left-back Guerreiro latching on to Kane's rebounded strike and curling a shot into the top corner with the outside of his left foot.

England captain Kane then had his 23rd league goal ruled out by the video assistant referee as Leroy Sane was offside in the build-up.

Union Berlin manager Nenad Bjelica was then shown a red card following ugly scenes where he shoved Sane in the face twice.

Kane was booked in the final minutes as tempers frayed in Bavaria.
