Apparently Perez returned to his country as his mother had been involved in an accident. Mexico.
So mayB the team should have given him some Leave 'cos his mind won't be on the job anyway!
No team spirit there then, a) no respect for his sponsors, manager, engineers and b) no thought for the costs to the Team should they not get expected results this next couple of weeks.
As with Joffra Archer, I would sack him on the spot! However: with football all the Team could be carried on a coach to the next venue and incarcerated into an Hotel? so that no one gets the chance to slip off to see his dog/s .........
