Holtby, who joined Spurs from Schalke back in January, has seen his first-team opportunities limited at White Hart Lane this season after the north London club brought in seven new players during the summer transfer window.
“It’s always special to play against a buddy like Lewis Holtby,” Schurrle wrote on his blog on sportupyourlife.com.
“Both Germans, both players with the number 14 and both substituted. The only difference was that we played for two different clubs, he played for the Spurs, I played for Chelsea.
“Before the game against the Spurs we weren’t in contact, but afterwards we talked a lot. Lewis is a great guy and I’m proud that we’re friends. He will establish himself.”
