Five of the 24 Championship clubs are still looking to get their first deal over the line, while the likes of Boro have made just one new addition. Others have been quick to bring in new recruits, with Leeds, Bristol City and Stoke particularly active. We take a closer look at some of the best Championship deals so far:
1. Tomas Kalas (Chelsea to Bristol City)
Proven at Championship level following loan spells at Boro, Fulham and Bristol City, Kalas has finally left Chelsea on a permanent deal. The Czech centre-back has now signed for the Robbins on a four-year deal, becoming the club's record signing . Photo: Michael Steele
2. Mallik Wilks (Leeds to Barnsley)
Following an eye-catching season while on loan at Doncaster in League One, the 20-year-old winger was snapped up by Barnsley for an undisclosed fee. Wilks had signed a contract extension with Leeds until 2022 in January. Photo: Nathan Stirk
3. Nick Powell (Wigan to Stoke)
After three years with Wigan, the 25-year-old midfielder turned down a new deal at the DW Stadium before joining Stoke. Powell struggled with a hamstring injury in the middle of last season but was a key figure when fit. Photo: Steve Bardens
4. Ethan Pinnock (Barnsley to Brentford)
Another eye-catching signing for the Bees following Pinnock's impressive 2018/19 season for Barnsley. The centre-back played a key part in the Tykes' promotion from League One, with Daniel Stendel's side conceding the least goals in the third tier last term. Photo: Harry Trump
