Rodgers on Tierney pre-contract, Kyogo departure & Villa test

Celtic manager Brendan Rodgers has been speaking to the media before the Champions League match with Aston Villa on Wednesday.

Here are the key lines from his press conference:

• Celtic have agreed a deal with Arsenal to sign Kieran Tierney in the summer, but Rodgers admits "ideally" they'd like to bring him in in January. "It would be great" if that could happen, "we would like to do that," he adds.

• The need for cover at left-back has been heightened by the loss of Alex Valle, who is in Barcelona finalising a loan to another club, which was also confirmed by the manager.

• Rodgers believes it's been "a great achievement" by his side to be in the top 24, and says the players have worked hard to get there, but the "job isn't complete".

• He insists Celtic have come to Villa Park to play at the level they know they can.

• On losing the "iconic" Kyogo Furuhashi from his squad and Daizen Maeda being suspended, Rodgers says both have been key players, especially in Europe, but he has the squad to cope without them, giving others a chance to step in.

• Cameron Carter-Vickers won't play on Wednesday, he has a niggle but should be okay for Sunday against Motherwell.

• Rodgers was full of praise for his counterpart Unai Emery, calling the job he's done with Aston Villa "top class".

• He is expecting a big challenge against "a very good side", who like to counter-attack, but it's a test he's looking forward to.

• On John McGinn, a player he tried to sign for Celtic, Rodgers says he is "instrumental" for Villa and the move to England has worked out well for him.
