Arsenal have sold Krystian Bielik to Derby County for a fee believed to be in the region of £10m when add-ons are included.

Krystian Bielik has brought to an end his time at Arsenal by agreeing a permanent move away despite Arsenal reportedly wanting him to agree a new deal with the club before heading out on yet another loan.

That was never going to be an option for Bielik who said this summer, “My future is unknown but there is one thing I can say for sure: I will definitely not go back to the Arsenal U-23 team.

“At this stage it wouldn’t make sense.

“If I do not receive the possibility to join the first team permanently, I will have to look for other solutions.

“I feel like a senior player now so I want to play senior football.

“This is, however, not the right moment to discuss these issues as I want to be 100 per cent focused on the European Championship.”

Bielik arrived at Arsenal for £2.03m from Legia Warsaw at the start of 2015. Although his sale to Derby represents a healthy profit for Arsenal, there will be a hint of regret that we couldn’t get Bielik to renew with the club.

Arsenal will also have to pay Legia Warsaw €500,000 from his sale.

That being said, we no doubt have a healthy sell-on/or buy-back clause in his contract so who knows…

The fee, which is believed to under Derby’s previous record of £8m which they paid for Matej Vydra, will rise to £10m with performance-related add-ons.

Derby face Huddersfield on Monday night at the John Smith stadium in their opening Championship game that kicks off 7.45pm. Bileik is expected to be named in the squad.
