Arsenal are set to complete the signing of Legia Warsaw midfielder Krystian Bielik after the Polish club confirmed that the player is on his way to having a medical with the Gunners.

Arsene Wenger is a huge fan of the 17-year-old and believes that the youngster can be an integral part of the Gunners' setup for years to come. The north London club staved off competition from Bundesliga club Hamburg, who had taken the youngster on loan after Arsenal were dithering on meeting his asking fee.

"I'm going to London to fulfil my dreams. I hope I will become an Arsenal player soon," Bielik told the Legia Official Website.

Meanwhile, Arsenal's problems in the middle have been exacerbated by the injury to Mikel Arteta, who is expected to be out for up to three months after being operated on for a calf injury. The Spaniard has missed the last two months with the same problem and is unlikely to see much action this season following the setback.

Arsenal are currently fifth in the league table, one point below Manchester United for a top four spot while trailing leaders Chelsea by 13 points.

However, their injury problem has alleviated over the past few days, especially with the return of Mesut Ozil and Aaron Ramsey, both of whom were out of action for a considerable period.

Ozil made a substitute appearance in Arsenal's 3-0 win over Stoke City at the Britannia and has to play an important role if Arsenal has to beat the likes of United, Liverpool, Southampton and Tottenham for a Champions League spot.

Danny Welbeck is also expected to be available for their trip to Manchester City on Sunday while Mathieu Flamini is also ready to slot into the midfield alongside Francis Coquelin to neutralise the threat posed by Sergio Aguero.

Arsene Wenger is also looking to bring in reinforcements to strengthen his defence. The Gunners had to spend the major part of this season on their bare bones, after they failed to replace Thomas Vermaelen adequately in the summer.
