In-demand Shakhtar Donetsk midfielder Fred says he wants to wait until after the World Cup to decide his future.
The Brazil international is subject of interest from both Manchester clubs, with United and City hoping to seal a deal for the 25-year-old.
Though United were reported to be closing in on a deal to sign Fred before the World Cup, the midfielder would prefer to wait until after next month's tournament in Russia to decide his next move.
"I don't know what I'm going to choose," Fred said at a press conference on Thursday. "Maybe I'll decide better after the World Cup.
"My head is entirely with the World Cup."
The former Internacional man confirmed there was interest from both sides of Manchester, with a move to City nearly materialising in January.
"There's been some advanced talks since January, when I almost went to Man City," Fred said. "United talked to my staff and Shakhtar."
Fred moved from Internacional to Shakhtar in 2013, and said he was flattered to see some of Europe's biggest clubs have been following his progression.
"It's an honour to grab the attention of great coaches in Europe, from Manchester and from our own national team," Fred said.
"I think I am strong on the field, I am versatile, I can play in several midfield positions. Some coaches like that, it grabs their attention, it is a big deal for me.
"Versatility, quality, good passing … I think all that catches coaches' eyes."
