The Sky Blues midfielder has also praised the strength of the forward line ahead of the trip to Sheffield United this Sunday...
Coventry City midfielder John Fleck believes the spirit in the camp has contributed greatly to an impressive League One campaign so far.
The Sky Blues travel to Bramall Lane to take on Sheffield United on Sunday, with kick-off at 12pm as City look to continue their unbeaten run since September.
City face a busy Christmas period with games against Oldham Athletic, Port Vale and Chesterfield, looking to maintain their promotion challenge.
Fleck struggled to remember the last time City suffered defeat and he believes that shows the great confidence City have in the squad.
The City midfielder said: "It's not make or break but it's important we pick up results in this run of games. There are a lot of points available and we've got to take advantage.
"I'm struggling to remember our last defeat so that shows you how well we are doing this season and we'll go into every game thinking we can continue it.
"There's a great spirit in the squad and everyone is enjoying their football at the moment. It definitely contributes to our performances on the pitch.
"We all know it is going to be a challenge over the Christmas period but we've got enough experienced heads in the dressing room to lead us through."
Sheffield United haven't won in the league since October but did record a 1-0 victory over Oldham Athletic in the FA Cup last weekend.
City will face a few selection issues as James Maddison and Joe Cole are in contention and Fleck has praised the strength of the squad.
He added: "It's been great to see him back out on the training pitch. He just shows what an incredible talent he is and he's been great since he's returned.
"We've got a lot of strength in the forward areas at the moment so I don't know what the manager is going to do. I'm sure he's got a few headaches at the moment and there will be a few disappointed players.
"It is surprising Sheffield United are 12th. They've got a very, very good squad and one of the biggest teams in the league.
"It's only approaching the half-way stage of the season though and I'm sure towards the end of the campaign, they'll be right up there."
