Coventry City manager Tony Mowbray feels that the big test for his side which currently top the League One table will be Crewe Alexandra tomorrow night.
Crewe have a good record at the Ricoh Arena in recent years and speaking about the game tomorrow night to the Coventry Telegraph's Andy Turner and James Rodger, Mowbray said: : "The test is tomorrow night [against Crewe Alexandra] because one swallow doesn't make a summer.
"With Crewe coming to try to spoil our good start to the season it must be like a red light flashing for us.
"Every football team has to play with and without the ball and you have to balance that off.
"At the weekend they were as expansive away at Scunthorpe United and probably played their best football when they were 2-0 down but played better in their previous game.
"It's important our players stay focused because it's a campaign and a grind.
"Who knows what we're going to be like in February when the pitches are boggy and not so lush.
"It's a long, long season so let's not get carried away."
