On the July 1st 2006, Diego made the switch to the Green-Whites. Diego replaced Werder legend Johan Micoud as the chief playmaker. It wasn’t exactly small shoes to fill a 19-year-old who had just one season of European top flight football under his belt, but Diego put in a host of convincing performances across his first season.
On 13.08.2006, the new signing marked his first Bundesliga appearance with a goal and two assist against Hannover 96. To top it all off, he was named as the Bundesliga player of the month in his first month at the club. It was an award that he would go on to win a further four times. His statistics after his first season were more than impressive: 13 goals and 14 assists. Only one teammate, Miroslav Klose, scored more goals that season for Werder. Amongst the host of Diego’s goal was the unforgettable goal of the season against Alemannia Aachen in 2007. In the closing stages of the game, the visitor’s goalkeeper had headed into the Bremen penalty area for a free kick. After a weak free kick, Diego collected the ball from his own half and made the snap decision to go for goal. The Brazilian struck the ball and found the empty net from 63.8 meters out. Largely thanks to Diego’s exploits over the season, Werder secured a third-place finish that season in the league.
The success carried on right away in the following season, as Diego continued to deliver. His goal tally remained the same and he once again registered a double digit assist figure, his 11 not being topped by any of his teammates. The Green-Whites continued to improve and had a great season, finishing only behind Bayern München on 66 points.
