Richarlison: The Tottenham striker will be out for seven weeks due to a hamstring injury

Tottenham Striker Richarlison has been ruled out for up to seven weeks with a hamstring injury.

The 28-year-old is Tottenham’s top scorer this season, with seven goals in 21 Premier League matches.

Thomas Frank’s side host West Ham in the London derby on Saturday (15:00 GMT) and have won just once in their past seven matches in all competitions.

They were knocked out of the FA Cup by Aston Villa at the weekend and currently sit 14th in the Championship.

Midfielders Lukas Bergvall and Yves Bissouma are back in action, while full-back Destiny Udoji and striker Dominic Solanke could feature against the Hammers.

Tottenham have signed England midfielder Conor Gallagher, 25, from Atletico Madrid for £35m, with Frank hailing him as the “best signing” and “exactly what we need”.

“First of all, he is a very good player, with great experience in the English Premier League, as well as in La Liga, and he is the captain of the teams,” the Dane said.

“So, that character, that leadership, that experience, and he’s still young and has a lot of development to go through, but he’s coming in at a good level, bringing his pressing ability, his directness, his scoring ability, but also being able to find good positions on the pitch.”

Tottenham announced on Thursday that former Netherlands and Everton defender John Heitinga has joined the club as assistant coach.
