Still, a number of loan deals, free transfers and low-cost moves have gone through this month, with the necessity to strengthen squads all the great in an injury-hit 2020/21 campaign. Here's a look at 17 deals, including Barnsley, that could still go through before Monday's transfer deadline:
1. Scott Twine - Swindon Town to Luton Town
The League One ace is attracting a lot of interest, with Luton Town believed to be in the running along with Reading, Brentford and QPR. His manager has hinted that a deal could happen, but a suitable bid is yet to be lodged. Photo: Alex Davidson
2. Ben Davies/Ben Pearson - Preston to Celtic
The Preston duo are out of contract in the summer, and Celtic have been heavily linked with the pair throughout the month. The former looks most likely to leave, but Bournemouth could move for both of them before the deadline. Photo: Lewis Storey
3. Yannick Bolasie - Everton to Middlesbrough (loan)
Boro's long-term target almost joined in the last transfer window, only for the deal to collapse at the final hour. This time around, it looks like Neil Warnock will get his man with time to spare. Photo: VIRGINIE LEFOUR
4. Nathan Collins - Stoke City to Burnley/Arsenal
The Potters want to keep their teenage star until the summer, but could crumble if a lucrative late offer comes their way. Burnley are believed to have recently had an offer of around £4.5m turned down this month. Photo: George Wood
