#4 Rachid Ghezzal
West Ham fans will be well-known to the name of the Algerian wing wizard who is now plying his trade for Olympique Lyonnais. The 24-year-old was a target for a number of Premier League sides back in the summer and the Hammers were also in that list, as per the rumour mill.
A player whose contract runs out with the Ligue 1 outfit in the upcoming summer transfer window, Ghezzal could be up for sale for a bargain and Bilic should definitely try to lure him to the London Stadium.
Premier League clubs Everton and Arsenal are in the race for Ghezzal as per reports, but the East London club can offer him a key role at the club which the two bigger clubs cannot. A quick and tricky winger who can also play centrally and still only 24, Ghezzal would be a brilliant signing at the Olympic Stadium.
