United States Women's National Team star midfielder Carli Lloyd is playing with Manchester City on a short-term contract and was in the vicinity of the attack.
"Sickened by what has happened in Manchester. Thoughts go out to everyone. This is literally right around the corner from me. I am safe," Lloyd tweeted.
The Union of European Football Associations (UEFA) said in a statement that it does not know of any specific plots to attack the UEFA Europa League Final between United and AFC Ajax on Wednesday at Friends Arena in Solna, a municipality near the Swedish capital of Stockholm.
"Due to the tight security arrangements, UEFA urges fans to arrive at the stadium as early as possible, as detailed checks will be made at the entrances, resulting in potential delays in accessing the stadium," part of the statement read.
