Griezmann is winless in eight matches with Atlético this season.</p>.<p>The defending Spanish champion has struggled recently with only one victory in its last four matches, including a 0-0 home draw against Porto in its first Champions League match.

Youssef En-Nesyri hurt a muscle and had to be substituted early in the second half of the team's 2-0 win against Espanyol in the Spanish league on Saturday.</p>.<p>En-Nesyri had scored his third goal of the season in the first half. Sevilla is coming off two straight wins and is third in the Spanish league. The Group G match is on Wednesday.</p>.<p><strong>Porto unbeaten</strong></p>.<p>Porto hosts Liverpool coming off an unbeaten start to its season with five wins and three draws, including at Atlético Madrid to begin its Champions League campaign. Porto won its three matches at home by outscoring opponents 10-0.</p>.<p>Veteran central defender Pepe is still listed as doubtful for Tuesday's Group B match because of a left leg muscle injury sustained in the 0-0 draw against Atlético in Madrid.</p>.<p><strong>Weah goal</strong> </p>.<p>As the son of a president who was once among the world's best strikers, Timothy Weah has a hard act to follow. He's still searching for a first goal of the season when Lille travels to face Salzburg in Group G on Wednesday.</p>.<p>The 21-year-old American forward is the son of George Weah, who is Liberia's president since 2018 and won the Ballon d'Or in 1995.
