#2 The other Costa
Even though it was Diego Costa who finally got the goal that saw Chelsea through to the next round, it was the other Costa – Helder, who was the more impressive player on the pitch. The Portuguese winger is the most expensive EFL Championship player at the moment and after his performance against the Blues – it's no surprise Wolves signed him permanently this January for a club-record of £13 million.
Touted to engineer an upset against Chelsea by his own manager, the 23-year-old did just enough to be one of the standout performers of the night. Even though he was inconsistent at times and didn’t maintain a stable influence on the game, some of his movements caused the Chelsea backline some trouble.
He did well to outrun Pedro who was deployed as a wing back in the first half, but could only get a corner off of John Terry after his move. It was a contest that would continue during the entire match but Pedro eventually did get the better of him. The former Benfica player whipped in a couple of promising crosses for his teammates as well, but Chelsea defenders were always around to clear the danger.
