Barcelona striker Luis Suarez has admitted his frustration at finding himself unable to end his Liga goal drought, lamenting that "the ball doesn't want to go in" for him.

The Uruguay international netted for the first time in a Blaugrana shirt in Tuesday's Champions League win at APOEL but he has yet to open his Primera Division account since making his debut against Real Madrid on October 25.

Suarez had two major chances to score in Sunday's 1-0 victory at Valencia, which came courtesy of Sergio Busquets' last-gasp strike, but he was denied by a brilliant first-half save from Diego Alves before then being incorrectly flagged offside after tapping home with 20 minutes to go.

"It’s an odd situation," the former Liverpool striker told reporters after the game. "The ball doesn’t want to go in but I’m always working on it. 

"The goalkeeper saved the first one, but the second made me angry because I could see that I wasn’t offside. 

"I took a step back to make sure I was in the right position, in line, and that’s why I was angry. It was a fair goal."

Despite his disappointment, Suarez insists that he is capable of forming a prolific attacking triumvirate with fellow forwards Lionel Messi and Neymar.

"My relationship with Messi and Neymar on the pitch is improving all the time," the 27-year-old declared. "But there are other players in the squad who can also do their bit to help the team."

Indeed, Suarez was delighted that Sergio Busquets had decided a game in Barca's favour that could easily have gone either way.

"In games like these, you know you’re up against a tough opponent, and so you enjoy winning more and it strengthens the team," the ex-Ajax man enthused.

"Of course it could have been a very different situation. We could have taken a couple of chances and won the match, but then again, so could they."

Barca's dramatic win at Mestalla sees them draw back to within two points of Liga leaders Real Madrid ahead of Wednesday's Copa del Rey clash with Huesca.

Much of the talk after the match was on Messi being struck by a projectile after Busquets' late winner at Valencia, which bizarrely saw the Argentine booked after the referee perceived him to be time wasting.
