This January transfer window has been quite lively. The Covid-19 pandemic made clubs significantly alter their investment plans last year due to the sheer financial hit they had to absorb. As a result, the 2021 summer transfer window was a hectic period for clubs as several teams were forced to offload their top stars.Plenty of deals expected to happen in the January transfer windowMany high-profile players switched clubs last summer and this January's transfer window seems to be kicking on in similar fashion. We've already seen several high-profile deals go over the line. Philippe Coutinho has moved from Barcelona to Aston Villa on loan for the remainder of the season.Kieran Trippier has joined Newcastle United on a permanent basis. Ferran Torres completed a €55 million switch to Barcelona from Manchester City.

They’ve got a good relationship with Fiorentina because Lucas Torreira is on loan at Fiorentina with a buy option.“The problem is the player. That’s why it’s not at an advanced stage or close to being complete because at the moment from the player’s side and agent’s side, they’re not open to talk to Arsenal about a move in January.“It seems he wants to stay at Fiorentina until the end of the season and bring Fiorentina back to European football and then leave in the summer.
