West Ham United may have lost 2-0 to Chelsea on Boxing Day, but that doesn't take anything away from the superb season Sam Allardyce's men are currently having.
With 31 points already, West Ham are just nine points shy of equaling last season's entire total, and the summer signings made by Allardyce and co are a large reason for their upturn in results.
The likes of Aaron Cresswell, Carl Jenkinson, Alex Song, Cheikhou Kouyate and Enner Valencia have all enjoyed success this season, but the biggest surprise has to be Diafra Sakho.
The Senegal international, 25, joined from French side Metz for just £3.5m in August, and has racked up eight goals and two assists in just 13 appearances for the Hammers.
Sakho is an athletically gifted striker with pace, strength and aerial ability, and he has transitioned seamlessly to the Premier League having impressed in Ligue 2 last season.
However, Hammers co-chairman David Sullivan told Soccer AM how manager Allardyce wasn't sure about signing Sakho, but Sullivan pushed for the deal to be done.
"I chose Sakho, it was a complete gamble," Sullivan said. "Without his goals, we would not be where we are. I was recommended him by Karen Brady’s brother this time last year, and we followed him."
"I know it was a jump of divisions, but he is very quick, and a great header of the ball. It was the last day of the transfer window, and Sam didn’t have a transfer target, and as much as he didn’t want Sakho, I said let’s take him," he added.
The slight inconsistency in the story is that Sakho actually joined West Ham in the middle of August rather than on deadline day, but Sakho's agent has also told the tale of how Sullivan was the one who signed Sakho, not Allardyce - and he certainly deserves credit for that, even if he's getting his dates mixed up!
