Chelsea are lining up their targets as they set about boosting their fortunes in front of goal.The Blues have drawn four consecutive games, remarkably not scoring a goal in any of their last three, furthering calls for reinforcements this month.Alvaro Morata arrived in the summer for a club record fee of £60 million but the 25-year-old has struggled to replace the goals of international teammate Diego Costa.The Spaniard has scored a decent 10 goals in 20 Premier Leauge games, although he hasn't quite lived up to the status as the club's main source of goals.Costa's goals fired Chelsea to the Premier League title last year but a falling out with manager Antonio Conte saw the player return to Atletico Madrid.Backup striker Michy Batshuayi has never remotely looked like being Conte's go-to player and there was much surprise in the summer when a second forward wasn't signed.Fernando Llorente, a player Conte worked with at Juventus, was certainly chased - only for Tottenham to beat Chelsea to the punch.But now Chelsea have reportedly learned their lesson; this time they won't put all of their eggs in one basket as three potential signings are being considered.The Telegraph reports that West Ham's Andy Carroll, Crystal Palace's Christian Benteke, and Red Star Belgrade’s Richmond Boakye are all being targeted.The three represent a clear goal for Chelsea - a target man to take pressure off Morata.Recent talk that manager Roy Hodgson has lost faith in Benteke could certainly open up the chance for Chelsea to tempt the Belgian away, although Carroll appears to be the main target.Speculation has been around for weeks that the former Newcastle and Liverpool striker was being lined up by Conte, although recent dealings at West Ham complicates matters.David Moyes has three strikers to choose from at the moment, but it's no secret that Javier Hernandez and Diafra Sakho are available for talks.Hernandez has been strongly linked with a move back to Manchester United - especially being a player that Jose Mourinho has openly declared that he wouldn't have sold - while Sakho has been suggested as a target for Palace.If Carroll truly is the one that Conte wants, then they may have the key to the deal sitting on their bench.The Telegraph again suggests that the Hammers would be open to a loan-exchange with Batshuayi  - meaning the player might finally be of use to Conte after all.The targeting of Carroll hasn't gone down too well with Blues fans, with many taking to Twitter to voice their displeasure.:
