Coventry City manager Mark Robins thinks their Carabao Cup game against Watford will be the toughest game of their season so far.

The Sky Blues' boss has seen his side go five games unbeaten at the start of their League One campaign, while the Hornets have lost all three of their matches so far.

However, Robins thinks there is still a gap in quality between the two teams.

"We are two divisions below them," he said of Watford.

"And they have got some unbelievably talented players, so whichever side they put out, it's going to be a tough game.

"But it's a game we can go and enjoy and try and progress - it's going to be our toughest game of the season."
