West Ham defender James Tomkins is backing new signing Victor Moses to have a big impact at the club after joining on a season-long loan from Chelsea.
The Nigerian winger is surplus to requirements at Stamford Bridge and spent the last couple of campaigns on loan at Liverpool and Stoke City, appearing 19 times for either club and bagging one goal for the Reds and three for the Potters.
Tomkins is familiar with the 24-year-old from their time together with the England Under-21 team before he switched national allegiance to Nigeria, and expects him to provide a threat for the Hammers.
"I know Victor Moses fairly well from our time playing together for England," he said. "He was brilliant for Stoke last season and is a nightmare to mark. The lads have already seen that in training.
"He can be a match winner on his day and I will try and help him settle in as I know him well. He is a similar age to me and he wants to play games.
"He is playing for a massive club like Chelsea and they have offered him a new deal which shows what they think of him.
"But for him to come here and play first-team football is something he is seeking to do. I think it is good business for the club and we have strengthened areas of the squad that we needed to and it was great recruitment."
Moses could make his debut for the Hammers in their next Premier League match against Newcastle United at Upton Park on Monday.
