Two players who look set to play key roles in the Championship are Jack Colback and Aleksandar Mitrovic.

However, in the ultra competitive second tier, the two Newcastle players are going to have to make a special effort not to be missing large chunks of the coming season.

Both Mitrovic and Jack Colback served suspensions last season and indeed the midfielder has been suspended twice in each of the two seasons he has been at St James Park, with a staggering number of yellow cards.

The two players feature in a list of the Premier League players with the worst disciplinary records of 2015/16.

In fact the Newcastle pair are second and third on the list with only Victor Wanyama rated worse after three reds and four yellows.

The list has been put together by the Express and rates red and yellow cards against number of minutes played last season, with extra weighting obviously for reds.

Jack Colback has has 24 bookings in league games in two seasons at Newcastle compared to 18 over the course of the previous four years. This represents a serious increase and makes the midfielder a liability at times, both with games he misses and daft yellows that leave him having to curb his game in matches.

Whether he is trying too hard for the club he supported as a kid, or he has been asked to do a job that has taken him further out of his comfort zone (gets regularly caught out of position or in possession, with lots of bookings for grabbing players when he knows he can’t recover and catch them), Jack Colback will have to be a bit more clever in the Championship.

Speaking of clever, Mitrovic was booked within seconds of coming onto the pitch in his first two appearances as a sub and in only 22 Premier League starts, managed to get two red cards. The second one meaning he already misses the first four games of the coming season.

Considering the striker had ‘only’ picked up two previous red cards in league matches in over 100 games before he joined Newcastle, also points to a significant increase in his lack of control.

No doubt his frustration at trying (and often failing) to compete at the higher level last season was a major factor and hopefully the less demanding second tier will allow him to relax and be more productive.

However, Aleksandar Mitrovic will have to be clued up and understand that Championship defenders will be looking to target his fragile temperament and attempt to wind him up on a regular basis.
