Luis Enrique has called on Barcelona to improve their penalty taking after Luis Suarez missed another in a record-breaking 5-1 win at Rayo Vallecano on Thursday.
Barca set a new Spanish record by reaching 35 games unbeaten in all competitions in a rout of nine-man Rayo, Lionel Messi scoring a hat-trick for Luis Enrique's men, who are now eight points clear at the top of La Liga.
However, with Barca leading 3-1 in the second half, Suarez spurned a golden opportunity to get his name on the scoresheet, seeing his penalty saved by Juan Carlos.
The miss marked Barca's seventh in 13 attempts, and Luis Enrique admits it is an area of concern.
"We are not successful in the penalties. We have to improve in this aspect, no doubt," he said.
"We played a good game. When we are at this level it is difficult to stop us.
"The end of the season is coming. It is the best part. The most beautiful part of the season is coming now and we have to wait to see [if] we get what we deserve."
