Portsmouth striker Ben Sahar is to sue the Moldovan FA after gashing his knee on a sprinkler during Israel's 2-1 win in Chisinau in a World Cup qualifier last month.

The 19-year old Israeli, who needed 11 stitches in the wound and was unable to play for nearly a month, says that the injury could have ended his career.

"There was a water system on the pitch, a sprinkler, and I fell on it. The Israeli FA are going to sue and, to be honest, I am going to sue, too," said Sahar. "The worrying thing is it could have been even worse as it could have caused some long-term effects. In the end, I am happy it was for only three weeks. It affected my availability for the club and those two weeks out kept me away from the team I want to play for. Now I am going to sue them so we will see."

Meanwhile, Sahar scored for Portsmouth reserves in their 2-0 win over Aston Villa reserves earlier this week. It was the Israeli's first game for Portsmouth since sustaining the knee injury when playing for Israel in early September. He also made Pompey's second goal for Jerome Thomas.

He reportedly told Israeli team-mates that he is angry with Chelsea for making life awkward for him at Fratton Park.

Earlier this month, Chelsea refused to let him play for Portmouth reserves against Chelsea reserves, invoking a clause in his loan contract that he cannot appear against the Blues, thus hampering his comeback after injury. Chelsea have refused to allow him to play in Portmouth's Uefa Cup campaign so he will not be cup tied if he returns to Stamford Bridge in January.
