The first step when you take a team as its manager is analysis of the team's squad. I'm going to do this with Wigan players now.
Goalkeepers
There is no competition for a place in the first team. Kris Kirkland is certainly the most strong keeper of Wigan. Former Liverpool player has high values of Reflexes, Jumping, One On Ones, Handling, Positioning attributes. Rather young for goalkeeper - only 26 years old. Giant height - 199 cm. The only suspicious thing is his weakness in coach report: "Kirkland is a player who may be fairly susceptible to injuries". It seems I should think about other first team goalkeeper if I have enough money.
Defenders
The most high valued and, as far as I believe, strongest defender is Titus Bramble.
He seems to be rather fast and reliable central defender who has stable good characteristics important for DC.
Another good and somewhat versatile guy in defence is Emmerson Boyce. He can play either DC or DR. Has strong fitness attributes and good defending ones. First team footballer, certainly.
Young Andreas Granqvist (22 years old) is pure central defender having great Determination and Jumping. All other important attribute values are high apart from Pace and Acceleration (both equal 10).
Fitz Hall is an average central back in my opinion. This is because of his Positioning=10 and Marking=12. What's interesting he is rather versatile and can play right defender, DMC and even FC (!). I think this guy can be good substitution.
There is another defender who is very strong - Mario Melchiot. And seems he is even better than Titus Bramble. Ex-Chelsea player is fairly determined right back with high Tackling and Strength. Gets forward whenever possible. In the coach report he is rated by 5 stars.
The closest concurrent of Mario Melchiot will be Ryan Taylor. And Taylor is not only right back, he is D\WB\M R. His best skills are Stamina and Corners. And what is good - Ryan is only 22 years old and can be trained into impressive winger, I believe.
Salomon Olembe from Cameroon is a guy who will play on the left flank of defence or midfield. But I'm not excited about his attributes: they are rather poor. Though he has good Pace and plays well both legs.
Andy Webster is Scottish central defender who is already on loan at Rangers. He is rather versatile player whose highest skills are mental.
Midfielders
I will start review of half-backs from Paul Scharner because he can play either MC, DMC or DC. When it's necessary Paul can close the right flank. He is strong Austrian guy with 191 cm of height and all fairly good attributes (where the most high: Determination and Aggression - 16). Important team member, I'm sure.
Denny Landzaat. MRC. His peak of fame happened few years before in AZ and Holland national team. At the moment he looks experienced, loyal and team-working midfielder.
Michael Brown - pure central midfielder (the best of all midfielders). Known for being Tottenham footballer earlier. Bought from Fulham.
He is exceptionally good team player and consistent performer. Brave, aggressive guy with brilliant Stamina, Natural Fitness, Determination, Work Rate. Can be leader of the Latics.
There is also highly skillfull in technics Jason Koumas - one of leaders of Wales national team. He costs $10M being the most valued footballer of Wigan. Can play both legs, dribbles very well (I've already checked this in 2 friendly games) but, surely, selfish player with TeamWork = 8.
Experienced Josip Skoko has 50 caps for Australia, good Long Shots and Influence, ability to play in any part of midfield (MRLC). Nothing more that impressed me about him.
There is also cool AMRC guy loaned fromVillarreal - Antonio Valencia. Fast dribbler with Tackling = 17 (!). This is great loan deal and I consider him to be leading winger of the team (of course, if I will choose tactics with wingers).
Cheap Rachid Bouaouzan (AMRL) has wonderful Pace, Acceleration, Dribbling and low mental abilities. But considered fairly inconsistent performer by one of my coaches.
Kevin Kilbane. AML winger with 80 caps for national team of Ireland. Passing, Crossing, Off The Ball, Concentration, Work Rate and Strength are all 16-17. The only thing I don't like about him is low speed: Pace=11, Acceleration=9. The winger must possess high speed, I believe. Do not know what I will do with Kilbane taking into account this.
Forwards
Forwards is the most weak part of Wigan. There I can select Emile Heskey as the best one:
Tough guy with good Heading who can be Target Man for the team. Should play very fine together with the team: Teamwork=19 and Work Rate=18. Has many caps for England, former star of Leicester and has somewhat controversial years spent in Liverpool.
Julius Aghahowa. Former Shakhtar striker. Scored 14 goals for Nigeria. He has fine Acceleration, Balance and Aggression. Good physics. Other skills are rather average for forward.
And the last one is Antoine Sibierski. AMC/FC. 32 years old. Good team-worker who can win headers due to high Heading, Jumping, Strength and height.
The main thing I do not like about all my strikers is their low Finishing. They all have it not better than 13!
Totals
The total of squad analysis - there are a lot of rather average players who are considered very weak for such teams as Arsenal, Manchester United or Liverpool. If I want to gain more than survival during the first season, I should work on the transfer market getting more useful players for Wigan. And, of course, opened question is tactics choice!
