Squad update

Will Grigg and Luke McCullough were the main surprises when Michael O’Neill trimmed his 28-man provisional squad down to 23. Liam Boyce, Billy McKay, Daniel Lafferty, Michael Smith and Ben Reeves were all dropped from the final party.

Grigg got the nod over Wigan team-mate Boyce while McCullough was preferred to Daniel Lafferty, who paid the price for not featuring regularly for Burnley this season.

Final squad

Goalkeepers

Name: Roy Carroll
Caps/goals: 43/0
Club: Notts County (Eng)

Alan Mannus
7/0
St Johnstone (Sco)
Age 34 (19.05.82)
Canadian-born, he did did not play in any qualifiers, but his excellent form in the Scottish Premiership will likely see him used as back-up.

Defenders

Craig Cathcart
26/2
Watford (Eng)
Age 27 (06.02.89)
Central defender who is always reliable and can also play full-back on either side. A major factor in Watford’s promotion to the Premier League last year and progress in the FA Cup this term.

Jonny Evans
47/1
West Bromwich Albion (Eng)
Age 28 (03.01.88)
Plays alongside McAuley for club and cuntry, so not surprisingly they have an excellent understanding.Joined Manchester United as an 18-year-old.

Gareth McAuley
60/7
West Bromwich Albion (Eng)
Age 36 (05.12.79)
Had three centre-half partners during the course of the campaign. Rarely puts a foot wrong and a real danger from set-pieces. Became his club’s oldest-ever Premier League player in March.

Kyle Lafferty
49/16
Norwich City (Eng)
Age 28 (16.09.87)
