While a few transfers have already been confirmed in this window, there is more business that could be finalised before the end of the month.

Reports in England suggest that unhappy Tottenham Hotspur attacker Dele Alli is desperate to reunite with Mauricio Pochettino at Paris Saint-Germain, especially considering his lack of playing time under Jose Mourinho. The 24-year-old, who once appeared set for great things in north London, has featured only 12 times across all competitions this season, including just 74 minutes of Premier League football.

While Alli has reportedly been frustrated in recent months and might believe his future lies elsewhere, the rumour mill suggests that he could be replaced with a familiar face.

Denmark international Christian Eriksen, who left the Lilywhites in last year's January window, is said to be interested in returning to Spurs following a difficult 12 months in Italy. While his high wages might prove an issue, the playmaker reportedly hopes the move can materialise.

Ex-Germany international Mesut Ozil is said to be days away from being announced as a new Fenerbahce player after he and Arsenal reached an agreement to terminate his deal in London. The 32-year-old recently confirmed his move to the Turkish giants, but has not yet been officially unveiled by the club.
