The Blues, having been the ‘away’ team last time out, will be the ‘hosts’ this Tuesday and walk into the game with a crucial 2-0 advantage courtesy of goals from Mason Mount and Ben Chilwell.
Following that win, the Blues put up their best display under Thomas Tuchel this past weekend when they beat Crystal Palace 4-1 away from home and will be aiming to carry that momentum forward.
As for Porto, following the first leg defeat they were able to bounce back to winning ways, defeating Tondela 2-0 in the Portuguese top-flight.
However, it will take a monumental effort from Sergio Conceicao’s men to overturn the two-goal deficit from the first leg and book a place in the semi-final.
