Boss Nuno Espirito Santo has questioned Nottingham Forest's recruitment process in a surprise swipe at the club.
The Portuguese is unhappy with the speed of Forest's transfer business and feels the squad is ill-equipped to handle a European campaign.
Forest could spend close to £100m on Manchester City midfielder James McAtee, Ipswich winger Omari Hutchinson and Rennes forward Arnaud Kalimuendo in the next 48 hours, while there is also interest in Juventus midfielder Douglas Luiz.
Yet, before Sunday's Premier League opener with Brentford at the City Ground, Nuno outlined his fears over the lack of signings.
"Dealing with doubts is the worst thing you can have in football," he said, having guided Forest to seventh last season.
