Manager Harry Redknapp says everyone at Tottenham has Fabrice Muamba in their thoughts.
The 23-year-old Bolton midfielder collapsed during an FA Cup clash with Tottenham at White Hart Lane on Saturday, and it was later confirmed that he suffered a cardiac arrest.
The match was abandoned shortly before half-time due to the seriousness of the incident, and Muamba remains in a critical condition in The London Chest Hospital.
Redknapp looked on in horror from the touchline, and admits referee Howard Webb's decision to abandon the fixture was just.
"All our thoughts are with Fabrice, his family, (Bolton boss) Owen Coyle and the club," said Redknapp in a club statement.
"It was the right decision to abandon the game, everybody was in a state of shock and it wouldn't have been right to carry on.
"Football is the last thing on anyone's mind when an awful situation such as this happens. All we are thinking about now is Fabrice and his family."
Spurs chairman Daniel Levy echoed Redknapp's thoughts, and hailed the medical staff of both clubs, who collaborated on the field to aid the former England Under 21 international.
"Our thoughts are with Fabrice's family and Bolton Wanderers and we are all willing him to pull through. Events such as this put everything into perspective," Levy said.
"We are immensely proud and grateful to the medical teams at both clubs, their response was immediate and professional.
"Our thanks also to both sets of fans for their support and behaviour. Too often we read the negatives about football and yet last night, at a time of intense emergency and uncertainty, we saw the true humanity and empathy of the footballing family."
