Porto hasn't reached the semifinals in the UEFA Champions League since 2004, when it posted a pair of clean sheets against Deportivo La Coruna. The Dragons went on to defeat Monaco 3-0 and capture the crown in the competition for the second time in team history. In order to advance to the semifinals of the 2021 UEFA Champions League, Porto will need a huge performance in the second leg of its quarterfinal tie against Chelsea on Tuesday. The Portuguese side put itself in a precarious position as it suffered a 2-0 loss to the Blues in the opener of their matchup last Wednesday.

Kickoff is scheduled for 3 p.m. ET. The latest Chelsea vs. Porto odds from William Hill Sportsbook list Chelsea as a 0.5-goal favorite, while the over-under for total goals scored is 2.5.

Top Champions League predictions for Chelsea vs. Porto  

The model is leaning under 2.5 goals in Tuesday's matchup between Chelsea and Porto. While opponents have had difficulty producing goals in their Champions League meetings, the Blues haven't exactly been filling the net. Chelsea has given up a total of two goals in its nine matches in the Champions League, but has scored two or fewer in four straight contests and five of its last six. Olivier Giroud leads the Blues with six goals in the Champions League, but four of them came in one game, while Timo Werner has gone 12 straight matches over all competitions without a tally and has recorded only two goals in his last 33 outings.

Porto also has had its issues of late when it comes to offense. The Dragons have registered fewer than three goals in 16 consecutive contests and leading scorer Sergio Oliveira (17 goals) has tallied only once in his last six outings. Mehdi Taremi, who is second on the club with 12 goals, scored in a Primeira Liga match against Tondela on Saturday but had been blanked in his previous eight games, which is one of the reasons the model is leaning toward the under on Tuesday.
