Manchester United boss Erik ten Hag has indicated that he wasn't happy with the performances of Jadon Sancho and Tyrell Malacia during his team's match against Omonia Nicosia.United created chances to go ahead in the two teams' UEFA Europa League encounter on Thursday (October 6). However, they didn't take them and also conceded in the 34th minute after Malacia gave the ball away in their attacking half. Omonia swiftly countered and found the net, with both the Dutch left-back and Sancho failing to get back in time to stifle the Cypriot side's attackers.The Red Devils failed to respond and went into the break trailing their less-fancied opponents by a goal. Ten Hag swiftly made changes, replacing Malacia and Sancho with Luke Shaw and Marcus Rashford before his team returned for the second half.Speaking after the game, the Manchester United manager was asked if the duo had been substituted because of their role in the opening goal. He explained the reasoning behind his changes and said (as quoted by Metro):‘‘It was not what I was unhappy with. It was the movement with our ball, the width on the left side, for me was no good [in the] first half.’’Ten Hag added:‘‘The movement from behind the defending line, so I hoped with Luke and Marcus we could get more effect from that and in my opinion that happens.’’Manchester United@ManUtd A double change from Erik at the interval...#MUFC || #UEL twitter.com/ManUtd/status/…Manchester United@ManUtd Off we go again in Cyprus.
