Freddy Adu's first start with Belenenses lasted just a half as the hosts went down in defeat to Nacional at Estádio do Restelo in Lisbon.
Adu started up front for head coach João Carlos Pereira in a 4-4-2 formation but was unable to make an impact on offense for the home team. During the halftime break, Pereira elected to bring in Andre Almeida in place of the loanee from Benfica.
One of Adu's best moments from the match came early when his play down the left side earned the hosts a corner kick in just the second minute.
Fifteen minutes later, Belenenses had one of their few scoring opportunities of the first half when Jose Pedro's free kick from just outside the penalty area barely sailed over the crossbar.
The free kick was the result of a foul committed by a Nacional defender who was battling with Adu for possession after a cross had been played to the American forward.
The visitors notched the game's only goal in the 27th minute when Rúben Micael spearheaded a counterattack down the left side before crossing to Brazilian midfielder Leandro Salino whose shot deflected off the post and landed at the feet of Anselmo who poked the ball into the open net.
Adu suffered an injury scare three minutes before halftime when he collided with Nacional's Bruno Patacas. The foul on the former DC United man earned Patacas a yellow card and left Adu hobbling around for several moments as the half came to a close.
The second half proved to be much of the same for Belenenses whose lack of offense continues to plague the club at a startling rate. Pereira's squad have only netted a paltry four goals in seven matches.
Belenenses return to league action next on October 23rd when they host Olhanense.
