Chelsea have suffered a slightly underwhelming start to their Premier League season following their £200m+ injection of players over the summer.

The Blues have been very inconsistent thus far, with some of their new additions still settling into life at Stamford Bridge.

However, the wealth of talent at Frank Lampard's disposal is undeniable, but the manager may be looking for further investment when the January window opens soon.

With that in mind, here are the very latest transfer rumours and stories concerning Chelsea.

Blues chase Haaland deal

Chelsea are looking to accelerate their pursuit of Borussia Dortmund striker Erling Haaland, and bring the youngster to Stamford Bridge in January.

That's according to journalist Angelo Mangiante (via ESPN ), who is claiming that the Blues want to sign Haaland in January rather than the summer window.

However, unsurprisingly - given his goalscoring exploits for Dortmund - the German club do not want to sell him right now. Lampard will certainly have plenty of competition for the 20-year-old superstar, with European powerhouses Real Madrid and Manchester United also heavily linked with a move.

Atletico open Alonso talks

Spanish side Atletico Madrid have opened talks with Chelsea over signing their left-back Marcos Alonso on a loan deal, according to a report from the Independent.

Alonso has not been a part of Lampard's first-team plans so far this season, and has not been involved in the Premier League squad since late-September.

The 30-year-old was born in Madrid, and spent 11 years at Atleti's Spanish capital rivals, Real, before moving to Bolton Wanderers in 2010. The Spaniard could move on loan to Diego Simeone's side, who are set to play Chelsea in the Champions League Round of 16 in late February.

What to expect in January

According to CBS Sports, Chelsea are more likely to trim down their squad rather than bring in more players in the January transfer window.

Defensive duo Emerson Palmieri and the aforementioned Alonso are looking increasingly likely to move away from west London. As well as this, Fikayo Tomori has been linked with a loan move away from Stamford Bridge, and Antonio Rudiger is also struggling with minutes.

However, if the right player does become available, then the Blues could look to make a swoop, the report claims.
