Dawson would welcome the potential arrival of Adebayor from Manchester City.
"He is a top player and whoever comes in is always going to improve the squad. If you want to do well, you can't have enough quality. A couple of additions would help us this season to freshen things up. You have always got to bring players in."
Dawson is similarly confident, albeit hopeful the club can retain the services of Modric.
"You want to keep your best players," Dawson said. "It is as simple as that. I have said it before and the chairman has come out and said he is not selling. The lads certainly want him to stay."
