Porto midfielder Marko Grujic admitted frustration after 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.

Grujic said afterwards, "It is difficult to reflect on this game.

"Chelsea had a good result, but we did not deserve this, especially after the first half, in which we had, if I am not mistaken, eight shots against one of them, and they scored.

"It is difficult accept this. There is no home factor here. If they scored two, we are also capable, anything is possible."
