Barcelona head coach Luis Enrique has hinted on a possible appeal of Luis Suarez's red card at Camp Nou on Tuesday by the club.Suarez who scored the vital goal as three players were dismissed in a 1-1 draw on Tuesday that secured the team's place in a fourth straight final with Barca winning 3-2 on aggregate was sent off for the first time in three years at Barca for a perceived stray elbow on Koke as the game entered stoppage time.Enrique is not holding out too much hope of having Suarez available for May's final against either Alaves or Celta Vigo who play on Wednesday in the second semfinal clash. "You have to appeal all you think is unjust, but when you look at the precedents, you see what normally happens with appeals," said Enrique."Apart from the anger that the players who will miss the final feel, the important thing is that Barca have won."There are now only two teams that can win the Cup and we are one of them." Enrique is quoted as saying on Sky Sports.
