There are reports that Chelsea are preparing a “monster offer” to sign Borussia Dortmund striker Erling Haaland.

The Blues have tried in vain to persuade the Bundesliga side to accept a players-plus-cash deal for the £150m-rated hotshot.

According to the reports, Chelsea are ready deliver a £135million bid for the Norway international.

The Sun had earlier reported how that has forced the Champions League holders to revive their interest in Bayern Munich’s record-breaking Robert Lewandowski as they try to give boss Thomas Tuchel the prolific goalscorer he wants.

However, Haaland remains Chelsea’s No1 target and 90mins claims they are now readying a ‘monster offer’ for the Norwegian.

And those claims have been backed up by various other sources since.

One of those was former Premier League and Norway star Jan Aage Fjortoft, who told ESPN that a ‘fantasy bid’ of £135m is set to arrive on Dortmund’s desk.

He said: “Chelsea have him as their main target.

“They would like to test Dortmund with a fantasy offer, and a fantasy offer will be around €150m (£135m) – double what they can get for him next summer.”

But Dortmund are determined to hold onto the striker for at least another season.

They have already lost Jadon Sancho to Manchester United and they are loath to lose their talisman as well.
