The French manager is clearly in need of another midfielder to support Cheick Doucoure in the middle of the park, with Will Hughes and Luka Milivojevic having both struggled for regular game time so far this campaign, making just three Premier League starts between them.
Vieira has often preferred Jeffrey Schlupp in the middle as an unorthodox midfielder, while Eberechi Eze and Michael Olise have both dropped into a deeper position on occasion.
Therefore another natural in midfield should be a priority for CEO Steve Parish in this month’s transfer window and it would perhaps not be a surprise to see the Eagles reignite their interest in Sow, after failing with a late move for the Switzerland international in the summer.
The Athletic claimed at the time that Palace could return for the 25-year-old this month when there was more chance of completing a deal with a fee of around €25m (£22m) likely to be enough to get the deal done.
This season has seen Sow make 15 appearances in the Bundesliga, in which he has contributed two goals and no assists, averaging a solid 6.71 rating from WhoScored for his performances, with the website also suggesting that he excels at interceptions, long shots and passing, which suggests that he can be an all-round midfielder in Vieira’s squad.
He also played every game Oliver Glasner’s side as they progressed through to the Champions League knockout stages, which emphasises the top-level experience he could add at Selhurst Park.
Express sports reporter Sam Smith was full of praise for the Swiss midfielder in late 2022, writing:
“First time properly watching Djibril Sow in this first half & been impressed. Progressive on the ball and combative.”
Therefore, while Palace fans will be disappointed that a move for Gallagher seemingly isn’t on the cards this month, the Eagles must put that behind them and bring in a midfielder such as Sow to help boost Vieira’s chances of a positive finish in the Premier League this season.
