Olympic champion Marcell Jacobs put an injury-ravaged season behind him to storm to gold in the 100m gold in the European Athletics Championships in Munich on Tuesday.

Jacobs, who was world indoor 60m champion in Belgrade in March, but withdrew before the semi-finals of the 100m at last month's world championships in Oregon, clocked a championship record-equaling time of 9.95 seconds. 

Defending champion Zharnel Hughes claimed silver in 9.99sec with another Briton, Jeremiah Azu, taking bronze in 10.13.

"This was a difficult season with problems, with injury," said the 27-year-old Italian, who has been beset by leg injuries and who competed with a heavily-strapped left calf in Munich. 

"My leg is not good and I am not happy about how the race went technically, there were some problems...But I am over the moon with the gold medal. After Olympic gold, I've now got the European gold. I've got to get the world championship gold now."

Meanwhile, home favorite Gina Lueckenkemper pulled off a shock by winning the women's 100m sprint. 

The 25-year-old, who won 100m silver in the last European champions in Berlin in 2018 and 200m bronze in 2016, threw herself at the line to clock 10.99sec for a photo-finish victory over Switzerland's Mujinga Kambundji.

Norway's Jakob Ingebrigtsen dominated the 5,000m to keep a repeat double bid on track. 

The 21-year-old, crowned world champion over the distance at last month's worlds in Eugene, timed 13min 21.13sec.

Croatia's Sandra Perkovic, 32, went out to a winning 67.95 meters on her fifth attempt for gold in women's discus, . 

It was a record sixth successive European title, the two-time Olympic and world champion having first won the continental competition in Barcelona in 2010.

There was also drama in the decathlon as Germany's Niklas Kaul snatched gold from Swiss rival Simon Ehammer on the back of a monstrous 76.05m in the javelin and a personal best of 4:10.04 in the strength-sapping final 1500m.
