Sunderland coming together - Etuhu
Etuhu believes there is a big improvement to come from the whole team as they continue their collective education.
He said: "I can sense it in every game, in every training session - everyone is getting used to and understanding each other's movement.
"When you play in a new team, you have to gel and get that team spirit the gaffer is trying to get into the camp - and we are getting that by the day.
"I am sure we will be better and better every week."
