Chelsea are set to step up their interest in several targets this week as they look to strengthen their squad ahead of the start of the new Premier League season.
And according to The Guardian, more signings could be made before the end of this week.
Chelsea's pre-season form has been less than impressive so far, with Saturday's 3-1 loss to Brighton the Blues' third defeat in a row.
The European champions have already spent close to £70million this summer, signing the likes of Marko Marin, Eden Hazard, and most recently Brazilian midfielder Oscar during the transfer window.
But Blues boss Roberto Di Matteo is known to be keen on bringing in a right-back and a striker before the end of the month.
Wigan winger Victor Moses is also on the west London club's radar and the 21-year-old could be Di Matteo's next signing.
The club are also hoping to add Marseille defender Cesar Azpilicueta to their ranks, although the two clubs are yet to agree a fee for the right-back.
Porto defender Alvaro Pereira is an alternative option to the Spaniard.
Pereira came close to joining Chelsea last summer and his agent has refused to rule out the possibility of a move this month.
"I spoke with Alvaro last week and he is calm," Flavio Perchmen told Antena 1 at the weekend.
"We are waiting to find out if there is any offer.
"We think everything will go well and that he can leave the club, but right now we do not have any concrete offer.
"Right now, he is 100 per cent at Porto. Last year, there was a 98 per cent chance of him leaving, but the remaining two per cent prevailed.
"Therefore, if someone makes an offer, we will look at what is best for the player and the club."
While Moses and a defender are signings widely expected to be made, just who Chelsea will bring in to replace Didier Drogba remains to be seen.
Napoli striker Edinson Cavani, Pereira's Porto's team-mate Hulk, and Atletico Madrid forward Radamel Falcao have all been on the club's radar for some time.
But all three would come with hefty price tags. Napoli want more than £60m for Cavani, Hulk would likely cost in the region of £35m, and Falcao around £30m, while could lead to the club looking at alternative options.
Chelsea have already failed with a £20m bid for Bayer Leverkusen's Germany international Andre Schurrle, but a £25m could be enough to convince the Bundesliga outfit to sell.
Chelsea's club's chief executive Ron Gourlay said last week that the summer spending spree is by no means over.
"If the right players become available at the right time we will sign them." he said.
"We've done that and we are still continuing to look at one or two positions and we will see how that develops over the next couple of weeks."
