West Ham could lose out on a minimum of £30million if Chelsea win the Champions League final on 29 May.

That is according to finance expert and Football Insider columnist Kieran Maguire, speaking exclusively about how West Ham could fail to qualify for next season’s Champions League even if they finish in the top four.

For that to happen, both Chelsea and Arsenal would need to win their respective European competitions, thus securing automatic qualification.

No more than five English teams can play in the Uefa’s flagship competition at once, and West Ham would therefore miss out.

The Europa League showpiece takes places three days earlier than the Champions League final, on 26 May.

Maguire explained that this sequence of events could be financially disastrous for the high-flying Hammers.

“It would be tragic,” he told Football Insider correspondent Adam Williams

“Qualification’s worth a bare minimum of £30m and it gets progressively more lucrative the longer you stay in the competition.

“It would be a huge missed opportunity from the point of view of their fans. They aren’t gonna qualify too often if we’re honest.”

“It would hit the fans and the players as much as the bank balance.”

West Ham are currently 5th in the Premier League standings, three points behind Chelsea in the last of the Champions League spots.

Chelsea take a 1-1 draw into their semi-final second leg against Real Madrid while Arsenal must overturn a 2-1 defeat to Villareal in the Europa League semis.
