Newcastle United chairman Chris Mort admits they'll make signings during this month's winter market.
"With the signings of Joey Barton, Habib Beye, Claudio Cacapa, Jose Enrique, Abdoulaye Faye, Geremi, David Rozehnal, Alan Smith and Mark Viduka, I am convinced we started the season with a much stronger squad of players than that with which we ended last season.
"The returns of Damien Duff, Shay Given and Michael Owen from long-term injuries, as a result of the hard work of the backroom staff and the players themselves, have also been very important to us.
"With these players added to some high-quality players already at the club, I think we all expected the team to be doing better on the pitch than it has been.
"While we have had some great results, such as the victories over Everton, Spurs and Bolton and the match against Arsenal, we have had too many disappointing results, such as the Derby games and the Boxing Day Wigan match.
"With the strength we have in the squad, I am hopeful that the team will soon settle into a winning run that will push us back up the table to where we should be.
"I would expect us to make a couple of further additions to the squad in January, but like any other club, we would prefer to add players in the summer transfer window than in January so that players have a chance to settle into the team.
"And January is always a more difficult time to extract high-quality players from their current clubs."
