When Crysencio Summerville arrived at West Ham United from Leeds United in the summer, there was optimism that he could take the Premier League by storm.

The Dutchman was named as the Championship Player of the Year last season after scoring 19 goals and adding nine assists in 43 matches for Leeds. It seemed almost inevitable that he would leave, however, after the Whites failed to gain promotion back to the top-flight.

Although there was talk that Summerville, 23, might end up staying at Elland Road, he left in August to join West Ham for a fee of just over £25million plus add-ons. He made his debut on the opening day of the season as a second-half substitute in a 2-1 defeat against Aston Villa.

Unfortunately for Summerville, he has struggled for regular game time at the London Stadium. In fact, the former Netherlands Under-21s international has started just six Premier League matches since his switch to the Hammers, featuring a further 12 times off the bench.

Summerville has scored just one goal for West Ham. That came, ironically, during a 2-1 win over Leeds' bitter rivals Manchester United in October. He has one assist to his name, setting up Niclas Fullkrug's late consolation when the Hammers were beaten 3-1 up at Leicester City.

It's safe to say Summerville's time at West Ham has been a disappointment so far and ex-Ajax and Borussia Dortmund winger Cedric van der Gun believes that the Dutchman may be struggling physically with the step up to the Premier League this season.

"He was brought in for a considerable amount, but that applies to several players there," he told the broadcaster Viaplay. "Fullkrug, for example. He actually disappoints me more than Summerville.

"The only thing I think of Summerville is that I have the idea that he is also struggling physically. In the Premier League, a lot is really asked of you physically. So maybe he will slowly grow into that role.

"But in a match like this (against Liverpool), where West Ham are missing a few players, you would have hoped he would be in. But then Lopetegui chooses others. Summerville is more of a substitute this season, but you still hope he can knock on the door a bit more emphatically."

With Jarrod Bowen out and West Ham struggling for form at the top end of the pitch, Summerville could be handed a rare start for West Ham during their trip to Manchester City on Saturday.
