"They have 10 points from the first few games plus the cup win at Bury so we know it will be difficult," he said speaking to the clubs official website.
"Roberto Di Matteo has gone in and they have hit the ground running this season. We are under no illusions that we have to go there and put in a decent defensive performance before we can start to attack.
"Whatever team they put out will be a good one. They have Simon Cox as a reserve striker and he cost £1.9 million so we know what we are up against. They are a strong side in all and they played some very attractive football last season under Tony Mowbray. They have stuck to their principals and carried them through to this season because they have the majority of the same players there,"
Robins added: "They have proved themselves in the past.
"I am sure that whatever the result the players will go out there and give a good account of themselves. We have a chance of winning the game because we are still in the competition and that is the way we are looking at it."
