Carlos Carvalhal says recent training ground displays have made his Sheffield Wednesday team selection "very tough".
The Owls moved up to fifth in the Championship - and five points clear of seventh-place Birmingham City - with a 4-0 win over Brentford last weekend and will be keen to keep their momentum going against in-form Preston North End on Saturday.
Head coach Carvalhal told the club website on Friday that, goalkeeper Joe Wildsmith aside, he has a fully fit squad to choose from at Deepdale, with captain Glenn Loovens and key man Sam Hutchinson both back in contention.
The pair were among 11 senior players to miss out entirely against the Bees and although perfectly happy to make those tough calls, the Portuguese says he would put all of them into his squad on current form - in contrast to comments he made earlier in the campaign.
“We don’t have any problems and we are with full energy," Carvalhal said in his pre-game press conference.
“I said in the past it was very easy to choose the 18 and now it is very tough because all the players are training really very well.
“We have put some players to play in Under-21s to have more tempo.
“Joe [Bennett], Alex [Lopez] and [Jose] Semedo played in the Under-21 and they are all really doing fantastic.
“To do the players justice, I would put all of them in the squad but this is the hard part for the coach. But I have no problem in making the decisions.
“It’s good when you can choose the best players for each game. Internal competition is very important, we are a full squad, with full energy and I believe we can be more strong in this game than in the past.”
