While there is plenty of cover in central defence to compensate for Dawson’s absence, Lennon is the only senior right-winger in the squad.
Lennon’s ability to combine attacking menace with defensive diligence is a key component in this team. While Villas-Boas wants him back as soon as possible, he knows that mistiming Lennon’s return could have serious consequences for Spurs’s season.
Meanwhile, former Tottenham midfielder Luka Modric insists he is happy at Real Madrid despite a difficult first season with the Spanish champions.
Although Modric, who moved to Spain from north London for £33million last summer, scored in the recent Champions League win over Manchester United, he has generally struggled to establish himself at Madrid.
There has been speculation about a quick return to England but Modric said: “There are no difficulties for me. I enjoy playing every day.”
