Southampton boss Mark Hughes is pleased with the winning experience they've added.
Saints have so far spent £23m in the transfer window, bringing in Stuart Armstrong from Celtic (£7m) and Mohamed Elyounoussi (£16m) from Basel.
Elyounoussi (4) and Armstrong (8) have won 12 trophies between them and having players with that winning history is a big positive in Hughes' book.
“It's important. The Premier League is a different level for them both but you gain a winning mindset, you get used to winning games," he said.
“Sometimes, when things start to go against you, sometimes you have to refer back to those memories to get you out of that spiral you've been in before.
“It's good that they're used to winning. They're used to high profile games; they've both played in Champions League games.
“That will help them because they will face players they faced in the Champions League, so it's not going to faze them.
“They've performed well against Premier League teams in the Champions League, so I'm looking forward to them progressing their careers and developing further because they come to us as very good players but now we've got the platform for them to become even better."
