The transfer mill is churning once again, with Tottenham believed to be lining up a move for Lutsharel Geertruida, the defender from Sunderland. Sources close to the club suggest they are exploring options to reinforce their squad ahead of the run-in. Tottenham remain optimistic, but the deal is not without hurdles. Liverpool, Sunderland and Marseille continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. So far in this season, Tottenham are conceding 1.61 goals a game (50 in 31), more than they'd like compared to the Premier League standard. The hope is Lutsharel Geertruida adds a bit of steel and helps make them tougher to break down. Reports suggest Tottenham are monitoring Noah Atubolu, Sehrou Guirassy and Niccolo Pisilli whereas Sunderland have not been associated with other players at this stage.
