Swansea defender Neil Taylor believes the next few weeks could be pivotal in their season. The Swans recorded a 5-1 win over Petrolul Ploiesti in the play-off round of the Europa League on Thursday.
That result has left Swansea on the verge of the group stages of the competition - and Taylor is well aware of the adverse effect that can have on domestic form.
"There is no question weeks like these will massively define our season," he said.
"It defined Newcastle's season last year. You have to have a big squad and be prepared.
"You have to rotate but always be competitive, simple as that.
"We got back at 3am when we played the away leg in Malmo, so coming back from Romania will be later again and gives you less time to prepare for the next game.
"You have to be ready to rotate the squad and have the players to do it - I think we have.
"It's what we want to do. We want to be going all over Europe and testing ourselves but remain strong in the Premier League. This is our first chance to show we can do that."
