Manchester City midfielder Ilkay Gundogan admits texting Jurgen Klopp after their Champions League quarterfinal draw with Liverpool was confirmed.

Gundogan, 27, won the Bundesliga under Klopp at Borussia Dortmund and scored in the club's 2013 Champions League final defeat by Bayern Munich at Wembley.

"I had four fantastic years with Jurgen," he said. "We won a lot of things together and we lived through many experiences. I'm very grateful for that and feel deeply connected to him.

"Maybe I can make up for the lost 2013 final and win this time. That would be the best feeling ever.

"He's a top guy who knows how to deal with players and how to treat them.

"He's proving all that again with Liverpool. Their attack is incredibly strong.

"We did chat a bit at the time of the draw. I said, 'See you soon' and sent him a little smiley emoji, to which he answered with a smiley as well."
