Celtic Football Club have admitted that they are unhappy with the Scottish Football Association after they decided to schedule friendly matches for Scotland, away to Peru and Mexico, in late May and early June, as per s report in the Scotsman.
As it stands, Celtic’s season could finish on May 19th, if they reach the Scottish Cup final as expected, and as such, the club’s Scottish internationals would only get about a week’s break before they had to fly to South America.

A revamp of the Champions League qualification period means that Celtic could face an additional round of qualifiers, which means that there will be very little time for the likes of Leigh Griffiths and Kieran Tierney to rest between the end of the current campaign and the start of the next.
Celtic’s chief executive Peter Lawwell will contact the SFA to express the club’s unhappiness at the scheduling, whilst Scotland’s Professional Footballers’ Association are said to back the club as they are concerned at how little rest players are getting between seasons.
