Flynn Downes revealed he was only made aware of West Ham's interest in him during a Swansea City training session earlier this week.
The midfielder was expected to join Crystal Palace, although his boyhood club West Ham made a late move to secure his services. As a result of the transfer speculation surrounding his future, he missed Swansea's pre-season clash with Colchester United at Fairwood on Tuesday.
After Swansea accepted an offer from the Hammers, Downes officially sealed a £9m move to the London Stadium on Thursday in a deal that could be worth up to £14m with add-ons. And the 23-year-old has opened up on how he found out about the interest from David Moyes' side.
