Cesc Fabregas feels the yellow card he received during Wednesday's 2-2 draw with Barcelona was "very unfair".
The Arsenal captain was booked shortly before half-time for a challenge on Sergio Busquets, despite appearing to win the ball.
The caution rules Fabregas out of next week's second leg, though the midfielder accepts he may not be able to take part at the Nou Camp anyway.
"It [the booking] was very unfair," he said after the match. "I thought I won the ball very well.
"I sprinted 50 yards for a yellow card. That was not really nice. But I could not play anyway now because of the injury."Copyright 2017 The Arsenal Football Club plc. Permission to use quotations from this article is granted subject to appropriate credit being given to www.arsenal.com as the source
