The 52-year-old spent the final few days of August hoping against hope that director of football Joe Kinnear would land one of his major targets, but he was ultimately left disappointed.
A statement issued on Pardew's behalf the day after the window closed spoke of his delight at the acquisition of loan signing Loic Remy and his optimism for the season, and he was maintaining a similar theme at his first press conference since on Thursday afternoon.
He said: "It's important sometimes to understand that we have a very good team. We invested 30-odd million in the last window, we have brought Remy in.
"We have brought a lot of young players here who I think, will hopefully, blossom. That's why they were brought here. The likes of Sammy Ameobi and Paul Dummett, part of my management is to develop players.
"Having said that, our fans wanted a marquee signing, probably, and that's what we were looking at, somebody that would really threaten the first team.
"But we couldn't get it over the line in terms of what we wanted and unfortunately that's the position we are in.
"But having said all of that, I still think we have got a very, very strong side."
The sooner this clown is gone the better. No Alan, we do not have a strong squad; we have a pretty good first 11, a few options beyond that and absolutely nothing else. The man's track record of developing players here is pitiful; Shane Ferguson has had his path blocked by an abysmal Jonas, young Adam Campbell has potential but has been played on the right in his handful of sub appearances, Sammi Ameobi is at the same level he was when Pardew came in 2 years ago. Young Paul Dummett is the one player I am hopeful can make it, but not under his woeful management and poor coaching team- bigal147
