Inside the Window: Man United's Next Superstar and Odion Ighalo's Dilemma

Memphis Depay is packing his bags, as a transfer worth up to £21.6 million from Manchester United to Olympique Lyonnais is being completed.

It comes days after Morgan Schneiderlin also left Old Trafford, moving to Everton.

United boss Jose Mourinho will consider both exits as good business, and we are waiting to see which other big-money deals will go through before deadline day.

Inside the Window is the B/R column that goes behind the curtain to reveal what is shaping up in the world's biggest leagues.

Here we look inside the Theatre of Dreams to discuss Antoine Griezmann's proposed switch from Atletico Madrid while also exploring deals involving Odion Ighalo, Carl Jenkinson and Lamine Kone.

Ighalo Prepared to Leave Watford

Odion Ighalo has become frustrated with his role at Watford and is ready to weigh up offers from other clubs.

West Bromwich Albion have contacted officials at Vicarage Road to discuss a fee, while the early indications from the player are that he would be keen on the switch.

Ighalo has started 14 of Watford's 21 Premier League games this season, and his only goal of the campaign arrived against West Ham United in September.

The striker has become aware that the Hornets are also being linked with new strikers, with the Mirror's John Cross most recently saying the club could bring in Fiorentina's Mauro Zarate on loan, and he is unsure how much game time he will get during the remainder of this season.

Ighalo has previously turned down offers from elsewhere to remain with Watford, but under Walter Mazzarri, the time has arrived for him to seriously evaluate his future.

In the past, he snubbed interest from China, per Matt Barlow of the Daily Mail. There is still an offer on the table if he has a change of heart, but his preference would be to remain in the Premier League.

Griezmann Deal Won't Be Affected by Man United's League Position

Antoine Griezmann is willing to join Manchester United next summer, even if they do not qualify for the Champions League.

As revealed by Bleacher Report's Insider Buzz in September, Mourinho has had his eye on the Atletico Madrid forward since the day he became manager at Old Trafford last May.

Mourinho believes he will be the long-term replacement for Wayne Rooney in United's squad, and the prospect of him pairing the Frenchman up with Zlatan Ibrahimovic and Paul Pogba is mouthwatering.

Momentum continues to build over Griezmann's potential switch, and the player is excited about testing himself in the Premier League.

Agreeing a transfer fee with Atletico Madrid remains a sticking point, but sources have indicated United are confident the player's desire to move will ensure it goes ahead.

United's outgoing transfer business in January will help with the move.

By selling Schneiderlin and Depay rather than allowing them to leave on loan, Mourinho ensured a good return on two players he did not feel had futures at the club.

Arsenal's Jenkinson Opens Up Search for New Club

Carl Jenkinson wants to leave Arsenal in January but has turned down his first chance of a top-flight move.

Crystal Palace expected to complete a deal for the full-back, but that potential switch has collapsed because the parties failed to agree to contract terms.

Palace are restricted by the deals they can offer as a result of the club's wage structure.

Jenkinson, 24, has played only 83 minutes of league football this season and realises he needs more regular action.

There is a small chance Palace will come back with an improved offer, but if not, there are five other clubs in the queue to speak to him, including West Ham and Aston Villa.

Sunderland's Kone Heading for London?

Sunderland will be facing a new defensive headache if Lamine Kone leaves in January.

The defender signed a new five-year contract in September, but he has a price tag of £18 million and could be sold if a club meets his valuation.

There is longstanding interest from West Ham and Everton, but Crystal Palace also now have him on their radar, as Eagles manager Sam Allardyce attempts to tighten up at the back.

Allardyce has even contemplated a move for Christopher Samba, who plays for Greek side Panathinaikos, as he searches for new defensive options.

It seems that was considered too risky, though, so Kone has been discussed as a possible target.

It is understood that Palace may take the opportunity to speak to his agent, who is currently in London.
