The defender moved to the Rams earlier in the summer after a spell with Burnley and put in 90 minutes in the recent friendly game against Burton Albion.
It was his first full performance of the pre-season schedule and Clement was impressed by the way the player made it through the game, with no other pre-season displays to fall back on.
“It is the only game he has played in pre-season, so to get 90 minutes out of him straightaway was a big plus,” Clement told the Derby Telegraph.
“It shows he is a fit guy and that he has worked hard in the short time he has been with us and it would appear he was working hard prior to coming to us.”
“He is going to be ready, no problem.”
Is it a risk to play him against Bolton?
Clement will already have a good idea of the side he wants to take into the opening match of the Championship season against Bolton.
It will be interesting to see if Shackell fits into Clement’s thinking because the intensity of the Championship will be far greater than anything Shackell can experience in pre-season.
It’s an issue of trust and the manager trusting the player to adapt quickly to that increased intensity and trust from the player that his manager won’t put him into a position that he’s not ready for.
Shackell had the chance to taste the intensity of the Premier League last year and hopefully he can use any determination to get back there to Derby’s advantage, whether he starts this weekend or in one of the club’s upcoming fixtures.
