What's one big change you will notice at Old Trafford?

In a new lay-out agreed with Erik, the home and away dugouts have been permanently switched so that the United manager, staff and substitutes will now be sat in the seats to the west of the half-way line – the dugout previously occupied by the away team.

Erik approved the move after visiting Old Trafford for the first time in May and noting how the old away dugout was closer to the tunnel, and to the half of the pitch where substitutes warm up.  

Switching sides will also position the home staff and players closer to the Stretford End – the traditional heart of the home support – and align the dugouts with the halves of the pitch in which the home and away teams warm up before the game.

The new layout will be in use for the first time in Sunday’s game against Rayo Vallecano, a day after the Reds play Atletico Madrid in Oslo. The two games against La Liga opposition on consecutive days will ensure that Erik is able to give the whole squad crucial game time ahead of next Sunday’s opening Premier League fixture against Brighton & Hove Albion at Old Trafford.

Fans will be waiting to find out if new signings Christian Eriksen and Lisandro Martinez will take part in either of the games, having both begun training this week.

There are a limited number of seats available for the Vallecano game, which kicks off at 16:00 BST on Sunday. Tickets are priced at £5 for adults and £1 for children for members and season-ticket holders. For non-members and non-season-ticket holders, the pricing is £20 for adults, £10 for under 16s and £50 for hospitality
