Porto coach Sergio Conceicao was pleased with Marko Grujic's performance for defeat to Chelsea.
The on-loan Liverpool midfielder featured for Porto in last night's 2-0 loss in the first-leg of their Champions League quarterfinal.
Conceicao went with Grujic over Sergio Oliveira and later said: "They are different players. [Grujic] He had a good performance, as well as the whole team, which left me satisfied. I was happy.
"Sérgio [Oliveira] was not here and it is not worth being with a what if. The 'ifs' now count for nothing. We are losing 2-0, we have to go looking for the win, we have to continue with this defensive solidity."
