Not sure how realistic they are but I'd like to see Matty James back here on loan. Chris Martin looks to only have played a handful of appearances for Derby this year (dont know if he's injured?) - but he's another one I'd love to try and get in (again presumably on loan).
But the names you mention don't guarantee Championship survival. A few don't get games for their current club for a good reason. If we were to get relegated this season, it's better to be there on a sustainable wage bill than one with Ritchie De Laet on it.
Jamie McGonigle is one for the future we are meant to be keen on if you believe a few rumours on Twitter. Ashley Fletcher (loan) and Oli McBurnie (perm) would add something different up top. If Yiadom goes would like Amari Bell. Not sure why he hasn’t moved up yet but is a cut above in L1. Have absolutely no idea who is available but a leader in central midfield. Someone who can take the pressure of Williams as well. Ryan Kent would add useful pace out wide, and wonder if Hecky is still interested in Connor Mahoney who can’t get a game at Bournemouth but looked a quality talent at this level for blackburn. I know Kent lacked end product with us before, but his pace on counter attack was a very real threat that teams had to worry about. And he could turn defence into attack quicker than anyone other than Isgrove we have now.
I'd imagine Chris Martin is on considerably more than we're willing to pay. And probably has a choice of clubs.
Jack Marriott is tiny he’s about 5 ft 8 and exactly the type of striker we don’t need. Zero presence. We’ve got a goalscorer in Bradshaw we just don’t have anyone to keep the ball up top for him to feed off. If I were looking at stats for a striker at the minute I’d be looking at headers won, fouls won, successful passes, successful dribbles, touches per game because that is what we are lacking. Bradshaw was poor in those areas when he played against us for Walsall in the Playoffs and he’s no better at them now. I don’t know who we could sign but I don’t believe looking at the top scorers in League one and Two is of any use to us as Bradshaw would be top scorer in those leagues playing for a top 10 side as was Armstrong and no one would have him back now as he didn’t suit what we needed as a team. What we need as a team is someone who is good at the attributes and skills above not just a goalscorer.
