The Belgium winger has been ruled out for around six weeks with ankle ligament damage, after leaving the pitch on a stretcher in Saturday’s goalless with Jurgen Klopp’s Liverpool.
The blow has come at a tough period for Spurs, who play eight games before the beginning of December, but former captain King thinks that Mauricio Pochettino has assembled a squad with enough quality to cope.
“Nacer is a big part of the team and his goals have been important for the team,” King told Sky Sports News. “But you know they have good players to come in and replace him.
“That’s the thing about the squad, they have the players to come in and replace him. It’s a good, young squad and we have great competition for places and I’m sure whoever comes in for Nacer will do a great job.”
Spurs face Belgian side Anderlecht in the Europa League on Thursday looking to keep hold of top spot after victory over Qarabag and a draw away to Monaco on October 1 took them to the summit of Group J.
Pochettino’s men return to domestic action on Sunday when they visit newly-promoted Bournemouth, and King is confident Spurs’ squad can cope with the hectic fixture list.
He added: “Liverpool was a good performance and the next one is Anderlecht and it’s important to keep going well in that competition and try and top the group.
“And then the next game [in the Premier League] is Bournemouth, so that’s the nature of the division and combining that with Europe is tough.
“But that’s why we have the squad we have. They are very fit under the current manager, so it shouldn’t be a problem.”
