Paul Cook believes it’s down to Pompey to find a way to combat defensive opponents after seeing his side thwarted at home again.
The Blues boss was forced to settle for a 0-0 draw as Pompey attacks failed to find a way past Yeovil Town.
But rather than lay the blame at their opponents, Cook accepted that the responsibility is his to crack the code.
Cook said: ‘It’s very disappointing for our players and it must be for the supporters in general to see teams “park the bus”.
‘That’s the way it’s going now.
‘Our job is to come up with a formula to beat it - that’s what we are all employed for.
‘Teams can set up how they want and I don’t disagree with it.
‘But supporters are paying money to see an exciting game.
‘They are not seeing too many at home, that’s for sure.
‘It was difficult on the eye. We did everything we could to win the game and in the second half it was a game we were never ever going to lose.
‘We needed that little bit of magic to win us a game but unfortunately, we couldn’t find it.
‘The important thing then is that you don’t lose the game and you move on.’
