"I hope people aren't thinking that we are going to bring a bus load of players in," he told BBC Radio Humberside.
"We have a big squad, look at the players who couldn't get on the bench - Wayne Corden, Marcus Williams and Andy Butler weren't even in the 16 at Bournemouth.
"When we do sign players we have to make sure we strengthen - not just for now, but next season as well.
"That's why we're looking at the likes of Rose - players who will become available and we are looking to strengthen as and when we can."
Meanwhile, Laws was delighted with the display of debutant Rose in Monday's 1-1 draw at Bournemouth.
"He had a very good game - he was very solid, passed the ball well and is a good player. He showed quality at times and I was pleased with how he played," he added.
