Graham Potter says that the stellar careers of Adam Lallana and Danny Welbeck can have a positive influence on the squad.
The pair have experience of playing at the highest level and have made 76 England appearances between them including World Cup finals.
He said, "Whenever you bring a player in the idea is to improve the squad. It doesn't always work out because it's not an exact science. You see that throughout football when people make good decisions with good intentions, but it doesn't quite work out.
"Adam and Danny have a pedigree, experience and a quality that is different to what we have. They have experienced football at a really high level as well so that's good for everybody.
"Then it's about how they can fit in and help our team because no team and club are the same."
The head coach talked about the higher number of Premier League goals that have been scored so far this season.
"We are in a period where there is no crowd, I am pretty sure at some levels that affects the game. It might mean why teams are creating more and the attacking play is able to function better.
"Maybe it is because the intensity of the crowd isn't there although it's only a small sample [of games played]. Let's see how things go in a few weeks when there is a bigger number of matches to assess."
Potter also praised how defender Tariq Lamptey continues to develop.
"He's learning all the time and will face different challenges game by game, but I thought he did very well against last Sunday against Palace.
"He stuck to his task. Some moments were better than others but that's what you expect.
"He's a young guy with a big future and we want to help him improve and keep taking those steps forward, his attitude and desire for the team is top quality."
