Speaking to Reading's official club website, Coppell said: "Tonight is another test on our journey. Coventry have done better away from home, they've had some great results; going to Birmingham and winning, but just like us they've been a bit inconsistent.
"Chris Coleman has really taken to management with vigour, he's got into the challenge at Coventry. I remember signing him from Swansea at Crystal Palace - his hairstyle's changed a lot since then!"
City supporters are being charged £27 for on the day admission for the game which kicks off at 8pm.
