Arsenal remain one point clear at the top of the Premier League after five games, with Liverpool and Chelsea hot on their heels.

Bulgarian champions CSKA Sofia will take legal action against the national football union after being excluded from the European Champions League.

CSKA were banned from European competition after the Bulgarian Football Union (BFU) said that they had failed to meet licensing criteria because they owed money to the state and creditors.

CSKA who won last season’s domestic championship without losing a match and earned a place in the Champions League third qualifying round.

“The BFU didn’t observe its own normative documents and didn’t treat CSKA as it should have done,” Lawyer Thomas Summerer told a news conference.

“It’s the BFU’s duty to take care of its members. Such a thing would have never happened in Germany,” added Summerer, who has worked with some of the leading teams in the Bundesliga.
