The summer transfer window has always been a very busy period for clubs in the Premier League.In recent years, Premier League teams have invested heavily to land their dream superstars. This year, though, while players are still being signed, there seems to be a change about how these teams are operating in the market.With the finances of clubs taking a big hit due to the COVID-19 pandemic, teams are making well-calculated moves before splashing the cash. That means they are conducting a thorough review of their squads to identify and eventually jettison star players surplus to requirements to fund new arrivals.On that note, here's a look at five such Premier League players who could be on the move this summer.#5 Divock OrigiDivock Origi has failed to impress at Anfield.Divock Origi dominated the headlines when he scored the famous goal that sealed Liverpool's epic 4-0 win over Barcelona in the 2018-19 Champions League semi-final. He scored the second goal against Tottenham Hotspur in the final as well. Unfortunately, the Belgian has failed to take off at Anfield since then.Origi was given the opportunity to impress by Jurgen Klopp last season, but he failed to capitalise on that. The attacker made nine appearances for the Reds in the Premier League in 2020-21, but registered no goal or assist. His only goal of the season came in a 7-2 victory over Lincoln City in the Carling Cup.Liverpool are prepared to sell Divock Origi to boost their funds in the summer transfer window. #LFC https://t.co/AateRgi0Kt— Football365 (@F365) March 15, 2021If reports are anything to go by, the Premier League giants already have the player's name on the market. Liverpool will hope to recoup about €20 million from Origi's sale this summer.#4 Hector BellerinHector Bellerin has been linked with a move away from the Premier League this summer.Hector Bellerin is another player who could be offloaded by his club this summer to make room for new arrivals.There have been several rumours linking the defender with a move away from Arsenal this summer.
