Chilwell went on to explain that it is important that Chelsea do not become “complacent” against Porto because they beat them in the first leg.
“If you look at the first leg, we knew going into that game that it was going to be very physical game,” he added.
“They are a very strong outfit with a lot of technically gifted players, but I think the manager touched on the fact they are a very proud team as well and it is the semi-finals of the Champions League up for grabs. It is definitely not over.
“We are not going to go into tomorrow complacent because we know the job is only half done. We know it is important we go into the game with the same mentality as we did for the first game.”
