With much of the squad having left to join up with their respective countries ahead of the upcoming World Cup qualifiers, Boyce has rued the missed opportunity to analyse the Latics' result and performance in the 2-2 against Everton.

"It's international week now and that means a lot of the lads flying all around the world,” Boyce told Click Lancashire.
“That makes it hard to analyse Saturday’s game, but we’ll get plenty of work done on the training ground and try to put right what went wrong.”
Wigan forfeited the lead twice against Everton, with former player Leighton Baines scoring an equalising penalty in the 87th-minute, but Boyce stressed that there were positives to take from the game.
“Overall I thought the performance was very good - we created loads of chances, we scored goals when we needed to and we were so close to what would have been a vital win,” added the Barbados defender.
“The positive was that we didn’t lose, and we can certainly take heart from much of the performance.
“We should be able to see out the game for another five minutes, but we couldn’t cope.
“At the end of the day, though, Everton are a good team, they grind out results and that was the case again.”
