​Former ​Arsenal star and current football pundit Paul Merson has slammed ​Everton for their transfer business, claiming that they wasted money on signing striker Richarlison from Watford  in the summer transfer window.

The Toffees shelled out a fee said to be in the region of £45 million for the 21-year-old with many surprised at the money paid for someone who started last season well but struggled as the campaign progressed and was criticised for his performances by the end of the season.

Merson though, believes that by paying such a high amount for the Brazilian, the Merseyside club had spoilt the transfer market.

"I think that's Richarlison signing that's spoiled the window if I'm being perfectly honest. I think that happened so early, and at £40m that set the benchmark. Teams then have gone, 'Well if you're getting £40m for him I want £60m, £70m, £80m, £90m and £100m," he said to ​Sky Sports.

"It’s a lot of money for Richarlison. I watched him in a few games last season and after the first six games, you would’ve paid that for him, but the next 32, you wouldn’t have bought him for that. Goalies will win you as many games as Richarlison will."

“You go through football in time with World Cups, Premier Leagues and Champions Leagues, those big tournaments that you win, no one does it without a good goalkeeper. I’ve got no problem with people paying £60m for a goalkeeper,” concluded the Englishman.

The 21-year-old Richarlison spent one season with Watford, scoring five goals in 41 appearances in all competitions. It will be interesting to see how he copes with the extra pressure that will fall on him due to his high transfer price.
