Mauricio Pochettino has declared that Tottenham’s squad needs to be strengthened in the January transfer window to compete on all fronts.

The Argentinian boss watched on from the touchline as Spurs were knocked out of the Champions League with a game to spare in Monaco, as Djibril Sidibe and Thomas Lemar struck to earn a 2-1 win and cancel out Harry Kane’s penalty.

Speaking after a match in which Tottenham were completely outplayed by the hosts, Pochettino was quoted by Press Association journalist Tom Allnutt on his personal Twitter account as saying that he is considering acquisitions in January.

“Maybe we need to add quality in our squad,” Pochettino revealed. “We have quality, yes, to compete in the PL but maybe to share both, we struggle.

“Maybe after 5 games we have not shown quality enough to share two tough competitions in the Premier League and Champions League.”

Kane continued his goalscoring return from injury with his fourth strike in three games as he converted a penalty to equalise.

However, that lead lasted just 39 seconds as Monaco took advantage of Spurs’ lapse in concentration through Lemar, who drove in a shot from a tight angle.

The loss leaves Spurs in third place and a spot in the Europa League as the most they can hope for, but they must still avoid defeat against Russian giants CSKA Moscow.

Bayer Leverkusen join Monaco in reaching the knockout phase, as Spurs poor run of form stretches to just one win in nine league and cup encounters.
