Tottenham Hotspur are now leading the race to sign an "outstanding" midfielder, and a deal could be done this month if they lodge a convincing proposal.
Spurs move into pole position in race for new midfielder
Thomas Frank has now confirmed he is setting out to make changes to his squad this month, after a mixed start to life in north London, saying: "We will be in the market. We are definitely interested in, if we can, strengthening the squad. We will do that.
"I've said it a few times before that things are important because of different types you can add to a squad.
"The main bit is the ones we add need to be ones that we really think can improve the team. Then, like normal, there can be outgoings if you want to try to make a sharp squad."
Brennan Johnson is one of the players who looks like he could be heading for the exit door, with Crystal Palace currently leading the race to sign the forward.
In terms of potential new additions, one position in which Tottenham are particularly keen to strengthen is central midfield, having recently identified AZ Alkmaar star Kees Smit as a target.
The Alkmaar youngster is not the only option, however, with a report from Caught Offside revealing Spurs are now leading the race to sign a more experienced midfielder, namely Bayern Munich star Leon Goretzka.
Indeed, the Lilywhites have now moved ahead of Arsenal and Manchester United in the race for the central midfielder, and contact has been made with his representatives, with Bayern potentially open to sanctioning a departure this month if a convincing proposal is made.
A free transfer in the summer could also be a possibility, with the 30-year-old's £218k-a-week contract at the Allianz Arena set to expire at the end of the season.
"Outstanding" Goretzka could be savvy addition to Frank's squad
Lauded as "outstanding" by former Germany teammate Sami Khedira, the Bochum-born maestro is highly experienced at the top level, having made 68 appearances in the Champions League, while he also knows what it takes to win, having lifted six league titles at Bayern.
The Germany international is also very impressive in possession of the ball, and poses an aerial threat, as showcased during his performances over the past year.
