article: 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.

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.
