Paulo Bernardo has opened up on the "boring" frustrations of the Portuguese league compared to the Scottish Premiership.
The on-loan Benfica star has struggled for regular game time since joining Celtic on loan during the summer transfer window.
But a hamstring injury to Reo Hatate has meant the midfielder has featured heavily in the Parkhead side's last two fixtures against Atletico Madrid and Hibernian.
And Bernardo detailed what the main differences are between playing in Portugal and Scotland.
He said: "In football here, the game is more intense. The game never stops. In Portugal, we lost a little bit of time in the game because all the players go down to the floor so the referee stops the game.
"It's a little bit boring compared to being here. That's the thing I have noticed most that it is different."
Meanwhile, Reo Hatate won't play for Celtic again until after Christmas.
The midfielder has been ruled out of action after the hamstring injury he suffered against Atletico Madrid.
Hatate had started the Champions League match but was forced off just minutes in as he struggled with the knock.
Now, Brendan Rodgers has confirmed Hatate has suffered a significant injury and could face a wait into the New Year to return to action.
The Celtic boss said: "We're not 100 percent on the exact timings of that, but he's certainly going to be out until after Christmas we think so that's a shame. I think it's a disappointment for him. He's had a bit of a broken start to this season and obviously this here will take him over the halfway point of the league.
"So it's very frustrating for him, especially someone who really commits himself to the game and his professionalism and everything he tries to do right.
"He's in a great place for that support from the coaches, manager and the medical team. The whole staff here will support him like we do all the players and hopefully we can get him back soon rather than later."
