Newcastle United are interested in bringing Demba Ba back to St James' Park.
The Senegal striker only left Tyneside in January, joining Chelsea on a three-year deal after they activated a £7m release clause in his contract.
Ba has made just the one appearance in the Premier League this season in the 2-1 win against Aston Villa.
With Romelu Lukaku's return from his loan spell at West Brom, Ba has come under pressure at Stamford Bridge, although he insisted in July that the extra competition would make him "play better".
Last season, the 28-year-old scored six goals in 22 games as the club secured a third-place finish in the Premier League.
With Jose Mourinho preferring to play without a striker in their 0 - 0 draw with Manchester United on Monday night, it goes down to show that he may not be relying on the services of his strikers in big games such as that. And with Fernando Torres Chelsea's last season top goal scorer with 22 goals being the only striker to come on to the pitch also points to the fact that Demba Ba has dropped in the pecking order at the club and may not be the first choice striker at the club.
Chelsea have completed the signing of Brazil forward Willian from Russian club Anzhi Makhachkala for a fee thought to be in the region of £25.5m.
The 25-year-old, who was poised to join Tottenham until Chelsea intervened last week, has been granted a work permit and has signed a five-year contract and will wear the number 22 shirt.
"I'm very happy to be here," Willian told the club's website. "It's been a dream of mine to come and play here.
"Chelsea are one of the best clubs in the world, and now I'm going to play for one of the best managers in the world, so I'm very happy and looking forward to it."
This will definitely be good news for all Chelsea fans but certainly not for some of the players already at the club who may see their playing time cut short and with the arrival of Samuel Eto looking more and more likely to happen Demba Ba maybe left with no choice than to go back to the club where he made his name in England.
