Negotiations between Chelsea and Roma for Alejandro Garnacho are developing, talkSPORT understands.But the Serie A side have hit a stumbling block, as they are yet to make a permanent approach for the winger.Garnacho is attracting interest from Roma and Saudi Arabia as his exit nearsGettyChelsea are only open to letting Garnacho go permanently, but Roma want to sign him on a loan with an obligation to buy.That obligation is understood to be conditional and worth a total package of around £34million.However, the Blues won’t be interested in accepting that offer, as they want a flat £42.5m for the Argentinian.talkSPORT had already revealed that that price was slapped on Garnacho, who signed from Man United for £40m last year.Roma, who will be playing Champions League football next season thanks to a third-place finish in Serie A, are going to have to match that fee, with the Premier League side unlikely to budge.And that is partially due to the volume of interest in Garnacho, with the Blues positive that one of his suitors will pay up.Chelsea have also received an approach from a Saudi Arabian club, so they could be the one to offer the £42.5m.Staying away Garnacho is expected to find his new club in the next two weeks, as Chelsea look to secure an exit for their forward.Due to his likely short stay at the start of the new campaign, the 22-year-old has not been training with the first team.He has been missing from the Blues’ pre-season so far, with full focus appearing to be on getting him a transfer away.Garnacho has not been training with Chelsea due to his imminent departureGettyNew manager Xabi Alonso appeared to confirm that on Monday too, as he spoke in his first press conference as boss.
