Bacary Sagna says Arsenal's penalty shoot-out defeat to Bradford City will act as a warning ahead of Saturday’s clash against Blackburn Rovers.
The Gunners were knocked out of the Capital One Cup by the League Two side in December, despite being heavy favourites to progress to the semi finals.
With Arsenal back in FA Cup action this weekend, Sagna is eager to avoid another giant-killing.
“Anything can happen in football,” he told Arsenal Player. “I don't think we deserved to go out when we played Bradford. They fought as much as we did. We created many chances but didn’t score and at the end of the game, we went out.
“Anything can happen and it was a warning. We know Blackburn are a serious team.
“We know it’s going to be hard, even [though] we’re at home. Everyone wants to win and everyone knows how important the FA Cup is for English football.
“We’ll go for it 100 per cent. I had a chance to win the French Cup back in the day and it was just great. I would like to feel the same.”
Tottenham Hotspur and Liverpool have already been knocked out of the FA Cup by lower-league opposition, and Sagna believes the gap between the Premier League and the Football League is closing.
“They have great players and we see more and more players from lower divisions reaching great teams,” he said.
“Zaha to Manchester United is a recent example. He played for Crystal Palace for many years, showed to everyone he’s a great player and even reached the national team playing for Crystal Palace, so it means a lot.”Copyright 2017 The Arsenal Football Club plc.
