Barcelona coach Luis Enrique is not concerned by Neymar's recent goal drought and is confident the Brazil forward will soon return to top form as the Catalans continue their bid to repeat 2009's historic treble. After an impressive first half of the season, Neymar has gone off the boil since the turn of the year and has not scored for the leaders in La Liga since hitting the opener in a 5-0 win at home to Levante on February 15. The 23-year-old looked particularly out of sorts in Sunday's 1-0 win at Celta Vigo and spent much of the game locked in an unseemly battle with Celta fullback Hugo Mallo.
