Leeds United made three signings in the January transfer window.
Evans wanted to make a number of changes to his squad in the January transfer window, but he was only able to bring in three new senior players.
Liam Bridcutt and Mustapha Carayol were brought in on loan from Sunderland and Middlesbrough respectively, while Toumani Diagouraga arrived on a permanent transfer from Brentford.
And Beagrie said: “Steve wants to re-address the slide and he has brought in some good players to help them out and stave off the threat of relegation.
“But the players that you need in that final third they are missing - Byram has left now, Wood is out [with injury] as well and the squad looks really threadbare.”
Evans made no secret of the fact that he was looking to make wholesale changes to his squad, but Leeds were surprisingly quiet throughout January.
The Yorkshire Evening Post suggest that the Whites could still be active in the loan window, with a deal for Norwich City striker Kyle Lafferty still being talked about.
Leeds certainly are short up front, with summer signing Chris Wood set to miss out on their FA Cup match against Watford at the weekend.
Evans currently has Souleymane Doukara and Mirco Antenucci available to play up front against the Hornets, with youngster Lee Erwin also an option.
