Sunderland boss David Moyes believes his Everton counterpart Ronald Koeman still has some way to go if he is to match his own achievements during his 11-year reign at Goodison Park.
Moyes returns to his former club on Saturday for only the second time since departing for Manchester United in 2013, having capped his reign by leading the them into the Champions League in 2005.
Moyes said: 'I think he (Koeman) is doing a good job. They (Everton) want to compete with the top clubs but I still think there's a bit to do to break into it.
