"Bolton will be as tough - or even tougher - than Manchester City because desperation will drive them on," Shearer told the Evening Chronicle.
"We may have won 10 Premiership games on the trot at St James's but we can't afford to be complacent. We've already suffered from that and Bolton cuffed us 4-3 on Boxing Day because of it.
"We feel we can beat anybody up here but we'll only do it if we give Bolton the respect we'll afford Arsenal, Manchester United and Chelsea when they come to our place."
And Bolton boss Sam Allardyce has warned that his players will not just roll over at St James, claiming: "We got a good point at Charlton on Saturday and must build on that. We have the platform to go to Newcastle and scrap for something."
