Joe Kinnear has praised his three new signings but admitted he was disappointed to miss out on Michael Johnson and Kieran Richardson.
Newcastle secured deals for Kevin Nolan, Ryan Taylor and Peter Lovenkrands during the transfer window and Kinnear feels they will strengthen his squad considerably.
The Magpies have struggled with injuries to key players all season and Kinnear accepts that he did need to bring in a number of new faces.
Speaking about Taylor and Nolan, Kinnear told Sky Sports News: "We are delighted to get the two boys in. They have shown the quality they have got.
"It has given us a great lift because we were in dire trouble as far as injuries are concerned.
"Kevin is a proven goalscorer. He is one I would hang my hat on and we were delighted to get him because he can play in several positions across the midfield.
"I was delighted with his performance on Sunday (against Sunderland).
"Peter gives us a real goal threat as well so I was delighted to get all three of them on board.
"All three will be involved on Saturday (at West Brom).
Manchester City rejected an £8million offer from Newcastle for Johnson on deadline day, while Sunderland also turned down what Ricky Sbragia has described as a 'cheeky enquiry' for Richardson.
Kinnear maintains that Newcastle did submit an official bid for the Black Cats midfielder, while he was also frustrated at his failure to sign Johnson.
"I would have liked to get the other two lads we were chasing but that did not materialise," he explained.
"It was a case of waiting to hear from them. At one stage we thought we had Johnson but the goalposts were moved.
"We waited and waited and waited and of course the clock was running down so we didn't get a reply back until an hour before they called time.
"It was the same with Kieran. We put what we thought was a decent offer in but it did not materialise."
