Portsmouth owe away fans 'more solid' form - Lang

Callum Lang has nine goals in 20 Championship games this season

Portsmouth need to "give back more" away from home after suffering a fourth successive defeat on the road in the Championship at Sunderland on Sunday, forward Callum Lang has said.

Wilson Isidor scored the only goal of the game as Pompey, who had Marlon Pack sent off after 67 minutes, remained without an away win since their solitary victory on their travels this season, when they beat QPR on 19 October.

"We probably created a few more chances late on than we did in the rest of the game," Lang told BBC Radio Solent.

"The ricochets just didn't fall for us throughout. We've got to take the end of the second half and keep moving forward.

"We were all together at the end with the fans. They've supported us amazingly, even after bad defeats.

"At Derby, I remember clapping the fans at the end and not a single person had left (after a 4-0 defeat on 13 December). The support's always there and we appreciate that a lot."

Four of Portsmouth's five league wins and 16 of their 23 points have come at Fratton Park, where they are unbeaten in five matches since 25 October, conceding only twice.

John Mousinho's players visit Wycombe Wanderers - who are second in League One - in the FA Cup third round on Friday before heading to a Blackburn Rovers side 14 places above them in the second tier on 15 January (both 19:45 GMT).

"They're going to be another two tough away trips," said Lang, who praised new signing Rob Atkinson after the on-loan Bristol City defender made a goal-saving block following his introduction as a substitute.

"We need to be more solid away. We want to give back more and we're working towards that.

"To come on and make your debut with 10 men is tough and [Atkinson] looked solid - he's a good addition for us.

"We just see who walks into the changing room and say hello. He's a good lad, so he'll fit straight in."
