Daniel Farke is considering drafting his trio of recent additions into the matchday squad when Norwich City travel to Brentford in the Sky Bet Championship on Saturday (3pm).
Onel Hernandez, Dennis Srbeny and Moritz Leitner all completed switches to the Canaries on Thursday during a hectic day of transfer activity.
"Today was their first proper session together with the lads," Farke told the media on Friday afternoon.
"We will decide if they will be in the squad on an individual basis. They won't properly know each and every detail of our game but we will make a short-term decision.
"Onel and Moritz are both eligible. We are waiting on Dennis' last bit of registration but we hope he will be available too.
"It was important to strengthen and we've got good lads in."
With City set to do without a number of players due to injury, including Ivo Pinto and Wes Hoolahan, their resources remain somewhat stretched this weekend.
"Brentford will be a tough game, 100 per cent," the Head Coach added.
"They are in a good shape and our situation will be better in a week. We can surprise them.
"We will look to be there with a really good performance. We are prepared to be competitive.
"It's a tough situation but we want to come back with the points."
