Video'Dear Liverpool': Watch Virgil van Dijk surprise the life-saving Alex

Alex's quick thinking and expertise helped save the life of John Harkin, who suffered a cardiac arrest when playing in an amateur football game earlier this year.

In the emotional video, John reveals how he was 'out' for the 27 minutes and would not have survived without the necessary pitchside treatment delivered to him by the opposition's centre-half.

Van Dijk gives both Reds a tour around the AXA Training Centre before they relive the afternoon that brought them together.
