As well as giving him the lowdown on Batshuayi, he has also been advising him on possible signing Thauvin, who he managed at Marseille. Newcastle will be keen to sell and Spurs could even get him on the cheap. Saido Berahino (West Brom) – in case they can’t get Batshuayi – A year on and it appears Tottenham are still interested in signing the England striker. Berahinos value has dropped on the back of a disappointing campaign with the Baggies, but Spurs could be ready to rescue him should they fail to land Batshuayi from Marseille. Sandro Ramirez (Barcelona) – the forward could cost less than £10m – Told by Luis Enrique he is not in the clubs plans for next season, Ramirez will be available for transfer. Likely to be sold for around £7.8m, the 20-year-old forward has been watched by Pochettino before and could a be cheap alternative to the likes of Batshuayi and Berahino. 6 Adam Lallana (Liverpool) – to provide depth in midfield – The England international has begun to look the part again after some initial struggles at Liverpool but, with Jurgen Klopp plotting raids for players like Mario Gotze, Lallana could be left fighting for a first-team spot. A £20m move by Spurs has been rumoured by The Sun, and would give them great depth in midfield. 6 6 Michy Batshuayi (Marseille) – Click to see more players Tottenham could sign in the summer… – Its now quite clear the Belgian striker will be leaving the Ligue 1 side this summer. Hes rated at around £30m by Marseille, and has been the subject of reports by Marcelo Bielsa, who is giving his advice to Pochettino. West Ham are also in the battle to sign the striker but the lure of Champions League football could be what makes his mind up. Yunus Malli (Mainz) – attacker to battle Alli for the no.10 spot? – Mauricio Pochettino and his scouting team clearly have a thing for Bundesliga stars. Having snapped up Kevin Wimmer from Cologne and Heung-Min Son from Bayer Leverkusen last summer, the manager could go back for Mainz attacking midfielder Malli this time. Worth around £10m, the Turkish star is also being looked at by Borussia Dortmund, and will battle Dele Alli for the no.10 spot if signed.
