Mikel Arteta has heaped praise upon Marcelo Bielsa ahead of his latest meeting with the Argentine boss on Sunday.
Arsenal play host to Leeds United in the Premier League, with the two managers set to go toe-to-toe for the third time in their career.
The Gunners defeated Leeds at the start of their FA Cup-winning campaign last season and were held to a goalless draw at Elland Road earlier this term.
Now, Arsenal welcome Bielsa's side to the Emirates Stadium as they look to end a streak of back-to-back defeats but they know they will be in for a tough test.
Ahead of the match, Arteta heaped praise upon Bielsa and declared his belief that Leeds should be higher up in the standings.
"I think he is a fantastic manager. I think we are really lucky to have him in the Premier League. He offers something different, a very particular style of play, very entertaining," he told Sky Sports.
"He's a very special character as well. We can learn and enjoy from him.
"In my opinion, they should be higher up the table for what they have done. Some of the games they lost, in an incredible way, it is what it is.
"Our expectations are high because they've been working together a few years now, they've developed the squad the way they want it and they are a very competitive side."
