Man Utd getting ready for Wrexham

[Getty Images] Manchester United head to Finland on Friday afternoon to start their pre-season campaign against Championship side Wrexham in Helsinki on Saturday (16:00 BST kick-off). United are not planning to announce their travelling party until just before departure, but with a combination of under-21 and under-18 group players on a separate trip to Germany for a couple of games on Friday, there have been some clues about who might be included in Michael Carrick's squad. This week, United posted a series of pictures from training - 25 players were shown, including four goalkeepers. Given Tyler Fletcher has returned to training this week as well after Scotland's World Cup campaign and Karl Darlow has joined United's goalkeeping ranks, that takes it to 27, which feels about right for a first pre-season game that will almost certainly see Carrick use completely different XIs in each half. Star attraction was £48m midfielder Andrey Santos , who completed his move from Chelsea on 13 July. Among the younger players pictured were defender Harry Amass, midfielders Jacob Devaney, Dan Gore and Toby Collyer, and striker Ethan Wheatley. They all spent at least part of last season away from Old Trafford on loan. Midfielder Jim Thwaites, defender Dan Armer and striker Chido Obi were also pictured. They were part of the United side that lost the FA Youth Cup final to Manchester City in May. Interestingly, JJ Gabriel wasn't shown and the fact the 15-year-old has not yet been back at Carrington for a week may signal he is not quite ready yet for his first exposure with the senior squad. Defender Matthijs de Ligt and striker Benjamin Sesko were not shown training on the actual pitches. De Ligt had back surgery in May after missing the second half of the season, while Sesko didn't play again after being replaced at half-time against Liverpool on 3 May with what Carrick described as a "shin issue".
