Celtic wanted to sign the former Hibernian midfielder John McGinn this summer.
The Scottish champions had multiple bids rejected for the 23-year-old and McGinn ended up joining Aston Villa in the Championship instead.
McGinn was very highly rated in the Scottish Premiership during his time in Scotland and Rodgers wanted to sign the midfielder as a long-term replacement for club captain Scott Brown.
Having lost the player to Aston Villa this summer, the Celtic manager has now expressed his disappointment. The Celtic boss even spoke to McGinn on the phone to convince him but the player had already made his mind up.
