Liverpool manager Jurgen Klopp is interested to see how Jose Mourinho's return to football will pan out, while long-time rival Pep Guardiola believes he will do a good job at Tottenham.
Mourinho is back in the game following his appointment as Mauricio Pochettino's successor, ending an 11-month hiatus since his dismissal as Manchester United boss.
He will renew rivalries with both Liverpool and Manchester City and will be tasked with bringing Spurs closer to those sides during his tenure.
Bournemouth manager Eddie Howe, who was briefly linked with replacing Pochettino, has no doubt Mourinho will still produce the goods.
"I was as surprised as everybody else watching from afar what happened this week, but Jose is an unbelievable manager and I think it's great for the league that he's back," Howe said.
"It's probably not ideal timing for us to go to Tottenham in his first (home) league game.
"Look at his record. I'd love his track record, the trophies that he's won, the things he's achieved in the game, it's incredible.
"So, for me, he's one of the all-time greats. I think the trophy cabinet says that. He's certainly got a lot more to give."
