Chilwell: No. Would have to lower his 200k/week salary to around 100-120k at least, and even on that money he's not worth it because of the injury record. We don't need a left-back anymore anyways, unless it's a really cheap or free option on reasonable wages.
Sterling: No. The risk is too high, it's more likely he flops than it is that he's a success, and I doubt he'd take a pay-cut from 325k per week to 100-120k per week as well, like he should, as with both him and Chilwell, that's the absolute max we would pay them unless we were out of our minds.
Out of the realistic options from the rest of their squad, Chukwuemeka would be the only reasonable pick IMO.
Ugochukwu would've been good, but he's already been loaned out to Southampton.
I would've taken Chalobah before we signed 3 defenders, but there's no need for him anymore.
Badiashile is a name that popped into my head but I doubt they'd be willing to include him in a deal, and he's already missed a lot of games for Chelsea due to injuries in just 1.5 seasons. There's also not much need for him either anymore to be honest, and at 23 he's still pretty raw and hasn't really improved since arriving at Chelsea. We already have a big work in progress CB with Yoro, probably best to avoid adding another one.
And I wouldn't want Madueke even if they'd let him go. Poch criticized his mentality and he just gives me the impression of being a massive cnut as well. (I was firmly of this opinion before the Wolverhampton post as well)
