Predicted Chelsea lineup (3-4-2-1) vs Porto, Havertz and Pulisic start
Chelsea are scheduled to host Porto in the second leg of their Champions League tie tonight. They have a handy 2-0 advantage from the first leg and are favourites to reach the last four of the competition.
Edouard Mendy is the Blues' undisputed choice in goal for the Premier League and European games. He is expected to start between the sticks.
The central defence may see a solitary change from the weekend with Thiago Silva replacing Kurt Zouma. He should feature in the middle of the back three with Cesar Azpilicueta and Antonio Rudiger either side.
Callum Hudson-Odoi is likely to be replaced by Reece James in the right wing-back spot as he is defensively more organised. In the opposite end, Ben Chilwell should continue ahead of Marcos Alonso.
Mateo Kovacic is likely to miss the game after sustaining an injury in the final training session yesterday. This should see the return of N'Golo Kante to the starting XI. He is expected to partner Jorginho in the midfield.
Further forward, no changes are expected. Mason Mount and Christian Pulisic are set to feature in the attacking midfield roles with Kai Havertz starting in the false number nine position.
Predicted Chelsea line-up (3-4-2-1): Mendy; Azpilicueta, Silva, Rudiger; James, Jorginho, Kante, Chilwell; Mount, Pulisic; Havertz.
