The London outfit have already sealed the signing of Hakim Ziyech from Ajax for £33million and also appear set to snap up highly-coveted RB Leipzig ace Timo Werner in a sensational swoop.
And with Frank Lampard significantly bolstering his ranks ahead of the next campaign, Shearer believes it is now more important than ever the young manager steers Chelsea to elite European football.
Werner, the Bundesliga’s second-highest scorer this term, is poised to move to Stamford Bridge and will snub interest from Premier League rivals Liverpool and Manchester United.
The club have also been linked with a move for Leicester full back Ben Chilwell, who is – according to The Mirror – keen on leaving to join Lampard’s revolution.
The Foxes are reportedly holding out for £85m for their academy product – but Shearer is ‘certain’ that Chelsea will continue to splash the cash.
He wrote in The Sun: ‘Signing Timo Werner is a huge statement from Chelsea – but it would be a kick in the teeth not to make the top four now.
‘Along with Hakim Ziyech, they have got two big-hitters through the door before the transfer window has opened.
‘I am certain there will be more to come, too, with Ben Chilwell also on their radar.
‘But these players will all be expecting to play in the Champions League next season, so it’s imperative they get the job done.
