Fulham boss Chris Coleman

Coleman's back four were run ragged by a lively Pompey forward line and the young manager concedes that improvements must be made.

"If we came here and scored three goals, I would expect to win the game,'' Coleman said.

''I did not expect us to give away four goals in the fashion we did.

"Going into half-time, I felt if we got another one we could go all the way, but they scored the next one.

"We are always going to score goals because we have got players who can score, but we can't defend like that.

"We have conceded six goals in two games and that is unacceptable.

"It is disappointing for us because, after last year when we were a hard nut to crack, maybe there are a few cracks appearing this year.

"We have to make sure we are a hard team to play against again."

Portsmouth boss Harry Redknapp

The Pompey chief set out with a highly offensive line-up and then had to sit back back and watch an attacking display from both sides.

"I felt we were going to be open, but I felt we could do damage to them," Redknapp said.

With anchorman midfielders Amdy Faye and Aliou Cisse on the sidelines, Redknapp had to play both Eyal Berkovic and Patrick Berger in an attack-minded set-up.

"I felt we didn't have anybody who could shut the game up," he continued. "I picked a team that was going to go forward, but we were vulnerable defensively.

"I had that type of team, even at 3-0, I knew it wasn't over."

Meanwhile, hat-trick hero Yakubu Aiyegbeni has quick to praise the contribution of new strike partner Ricardo Fuller - who also impressed.

"When we scored, they scored too and we were a little bit scared," conceded the Nigerian. "Ricardo did very well today, I think he's a very good player.

"It's a good feeling to be at Portsmouth Football Club. ''It's a good feeling when you have players like this. When you play so well, you deserve to win."
