Chelsea edge Liverpool out of FA cup. A night Costa also made headlines for the wrong reasons

Branislav Ivanovic's thumping extra-time header sealed Chelsea's spot in the League Cup final after an incident-packed 1-0 victory over Liverpool at Stamford Bridge on Tuesday.   However, the match was noteworthy for a series of flashpoints involving Diego Costa, including a stamping incident in each half on Emre Can and Martin Skrtel.
The Spain international was at the heart of more contention when he was denied a penalty by referee Michael Oliver after going to ground under a challenge from Skrtel just after the 20 minute mark.
