Maurizio Sarri has just over one week to plug the gaps in his Chelsea squad that were exposed by Arsenal during Saturday's 2-0 defeat.A new winger was what the Italian manager wanted at the beginning of January, but over the past few weeks his focus has changed to a centre forward.For all his talents, Eden Hazard is not a striker and his best position is out wide, while Alvaro Morata just isn't good enough and Olivier Giroud is regarded more as a back-up option.AC Milan's Gonzalo Higuain is the man Sarri is chasing and a loan move looks likely after Gennaro Gattuso said over the weekend that the Argentine wants to leave."I accept his decision," said Milan's head coach, per Sky Sports. "Surely he could have done more and maybe we could have helped him fit in better. I want to be honest with you."Gattuso's assistant, Luigi Riccio, then fuelled speculation by saying Higuain's proposed switch to Chelsea is 'in the air' - whatever that means."As for the transfer market, we are all grown-ups, we know how to deal with these situations," said Riccio after Milan's 2-0 win over Genoa, which Higuain missed."It has been in the air for a few days, but we will work with the players at our disposal."So what's the latest on Chelsea's pursuit of Higuain? Well, the Daily Telegraph's Matt Law has responded to Riccio's comments by saying the move hinges on other deals being finalised.Morata to Atletico Madrid is one of them and Michy Batshuayi has been linked with a loan move to Milan, so that could be another.Once everything else is in place, Chelsea should sign Higuain.

"In the air, as in 'in the pipeline'," tweeted Law. "It will be signed off once other deals are finalised. Should be completed soon."

Higuain hasn't exactly been on fire for Milan this season - he's actually scored less goals than Morata - but the 31-year-old will certainly add something new to Chelsea's attack.
