Newcastle United currently find themselves deep in relegation trouble.
The Magpies currently lie in 19th position in the table, picking up just two wins from 14 matches and seeing rivals Sunderland haul themselves off the bottom to move to just outside the drop zone.
But Bowyer feels the blame instead lies elsewhere, criticising the players’ attitude.
“But the way I look at it is, if Newcastle do decide to get rid of Steve, who are they going to bring in? Who is going to do a better job?” Bowyer questioned when speaking to talkSPORT.
“I just think it comes down to attitude. For example, they went 1-0 up at Crystal Palace and just folded, and ended up losing 5-1. The team’s attitude is just wrong.
“They’re not the type of the players who are going to respond if Steve gives them a rollicking. I think he’s doing that already, but he’s just wasting his time because it’s not having an effect.”
Whatever McClaren has told his players over the past two weeks hasn’t had the desired effect as the performances in the defeats to Leicester and Palace were dreadful.
Newcastle lack leaders in their ranks, and unless they bring in at least one or two new players in January then they are going to struggle to stave off relegation this season.
While an addition of Premier League experience would be welcome, the Magpies more importantly need to strengthen the spine of the team with a lack of organisation in particular a big worry.
