Yakubu's second half header was enough for Pompey's 1-0 win on Monday night - although we had chances in spells, Head Coach Jacques described it as a 'difficult night'.
But he insisted the lads want to put it right against Bolton on Saturday and that the two games in four days - the Carling Cup tie at the Reebok follows on Wednesday - were very important.
"Each team has difficult moments and this was a difficult night for us because we had injuries, we lost Thimothee Atouba and our captain Jamie Redknapp was suspended," he said.
"I would like to now put it right against Bolton on Saturday.
"We also had players away with their internationals teams and it is not easy for them to play three, four days after they come back. I think in two or three weeks we will have a good situation.
"For now though, it is important to win on Saturday. Bolton is a good team and we also play them four days later in the Carling Cup. These games are very important for us."
Jacques Santini quickly turned his attentions to our Premiership/Carling Cup double-header against Bolton after we lost our unbeaten away record at Portsmouth.
