The City Under-18s coach also believes Halesowen Town will provide a real test to the young players in the Birmingham Senior Cup...
Coventry City Under-18s coach Jason Farndon believes there is still work to be done after his side secured a 4-1 win over Swansea City at the weekend.
The Sky Blues have enjoyed a terrific start to the season having won four and drawn two games out of their first six matches.
Goals from Kyle Spence, James Maddison, George Thomas and Dion Kelly-Evans sealed the win at Swansea City and City are the only unbeaten side in the Professional Development League.
Farndon has praised City's determination to get the result but still believes the Sky Blues can improve further.
The Under-18s coach said: "It was a good team performance but not our best performance by any means. They just find ways to win games.
"It wasn't an easy game at all. They were a good footballing side but our work-rate was excellent and the way we took our chances was brilliant.
"Our counter-attack play was great but there is still plenty to improve on. I was really disappointed with the goal we've conceded.
"We've got to cut out those silly errors. If we work on them in training, then we could turn a good start into a good season."
Some of the Under-18s squad are set to be involved in the Birmingham Senior Cup game against Halesowen Town tomorrow night.
Farndon believes it will be a real test for the young players and says these sort of games will prove whether they can deal with 'real football'.
He added: "I'm looking forward to it. It will be a great experience for the young players to go up against an experienced side.
"A lot of the Under-18s might play at Halesowen and it will be a real test for them. It is real football and they will have to stand up and be counted.
"The defenders will have to defend and be strong. It will be a different type of game and it will be a different style we'll have to play.
"It is a difficult challenge but if they are going to be become professional footballers, it is a challenge they've got to come through."
