Wolves boss Gary O'Neil admits the summer transfer window has not gone as he expected.
The West Midlands club have lost two key players in the form of Max Kilman and Pedro Neto to West Ham and Chelsea respectively, and are still working to bring some players in before the window shuts.
Goalkeeper Sam Johnstone was announced as their latest recruit on Friday after signing on a four-year deal from Crystal Palace but there may also be some outgoings as Fabio Silva and Daniel Podence are expected to be leaving the club.
The Wolves boss told a press conference: "As we progressed through the window we missed ones that we thought would help us for different reasons – sometimes financial, sometimes the fact they have gone before we were ready to do it.
"We weren't able to do some bits we hoped we would and then the window became different for us towards the end.
"I did think the group needed some help from the outside and it didn't go quite as we planned it to go so it falls on me to make sure we are still able to compete.
"We have more depth, but we've lost two top players that we know can perform in the Premier League week in week out – obviously Max and Pedro Neto, who can be one of the best players in world football – so more depth but we've lost two really big ones."
Wolves travel to Nottingham Forest in search of their first points of the Premier League season following defeats to Arsenal and Chelsea in their opening two games.
The international break will follow the conclusion of the match and O'Neil added: "We approach Nottingham Forest knowing we have a big game in front of us, it starts 0-0 so whatever happened in the last one, it's gone.
"We need to find our own way to go there and be competitive, I think the transfer window and the way clubs have done business shows the Premier League will be unbelievably tough and competitive.
"So an opportunity to go away and show what we are made of, get the first win and get our first points on the board.
"I would expect it to feel like a big game. Off the back off two losses in the league, Nottingham Forest wanting to get their first home win, I will expect it to feel like a big game."
Boubacar Traore is facing another spell on the sidelines after he picked up a knee injury in Wolves' 2-0 win over Burnley in Wednesday's Carabao Cup tie.
The 23-year-old had just returned from injury but could have surgery on the issue which could keep him out for a number of months.
O'Neil said: "Bouba will be out for a little while, potentially needs surgery on his knee – not 100 per cent sure on the extent but it will be a few months.
"Disappointing, great guy and love what he brings to the group."
