Tuche has done a great work in his short time at Chelsea you could see the level of confidence in the team, 14 games unbeaten with 9 clean sheets says a lot about this team. This is going to be an exciting fixture as both are on the same level this season, they are the two underdogs in the competition right now.
In this round, all existing teams will have higher morale than before and must not underestimate other team before the match starts. Chelsea were reportedly very happy when they learned of the semifinal draw because they met Porto. I don't know why Chelsea are so happy because in my opinion Porto is not an easy team to beat. Porto's history in the Champions League is even better than that of Manchester City and PSG. It is no use underestimating them and now Chelsea must be wary of Porto's high spirit to beat them in the two leg of the semifinal.
