Brian McDermott is convinced Reading can win anywhere on their travels after their impressive Leicester triumph.
The Royals travel to Fratton Park tonight and for Pompey it is effectively another local derby.
Reading are buoyed by an eye-catching victory at Leicester on Saturday.
McDermott’s men beat the red-hot promotion hopefuls through goals from Noel Hunt and Hal Robson-Kanu, prompting Sven-Goran Eriksson’s side to be booed off by their own supporters.
Next up is Pompey, who have lost successive matches at Fratton Park this season already.
And the Reading boss believes his men can chalk up another defeat for Steve Cotterill’s side.
He said: ‘It will be another tough game. But I think we can go anywhere and win. I have no fear and the players have no fear of anyone.
‘Anyone who goes to Leicester this season has got to play well and work hard.
‘So we have to be delighted with what we’ve achieved.
‘We had a game plan, which we stuck to. Before the match we talked about us, our players and how we could hurt them.
‘I thought our passing was good, the organisation was good and I thought we were deserving winners.
‘We’ve a good bunch – give them a job to do they’ll do it.’
