Tottenham boss Mauricio Pochettino admitted there are still some problems in his squad after their shock Carabao cup exit to Colchester.
Spurs were defeated 4-3 on penalties by the Sky Bet League Two side after being held to a goalless draw at the JobServe Community Stadium.
Christian Eriksen and Lucas Moura both missed during the penalty shoot out which allowed Tom Lapslie to add another Premier League scalp to the U’s collection after they knocked Crystal Palace out in the last round.
Pochettino major concern at the start of the season has been about how his squad were unsettled, with the likes of Eriksen, Jan Vertonghen, Danny Rose, Toby Alderweireld and Victor Wanyama all uncertain about their futures.
Pochettino was hoping it wouldn’t matter so much after the European transfer window shut at the start of the month, but he says his side are still playing catch up.
“When you have an unsettled squad always it’s difficult and you lose time and then you need time to recover the time you lose,” the Argentinian said.
“That’s where we are. Maybe our performances are good but you need this extra, which is mental, connection, it’s energy to be all together, not to have different agendas in the squad.
“We need time again to build that togetherness that you need when you are competing at this level.
“We are in a period where it’s a bit tough for us but we keep working to find a solution.
“When this type of thing happens it’s about staying clear and fresh and calm. We’re trying to find solutions and we only need time.”
“They were tough, they defended well,” Pochettino added. “Of course the difference of the level is there and if you analyse the circumstances, yes we need to create more and be more aggressive in the final third.
“We did nearly everything good until the last third. Sometimes you score, sometimes you don’t.
“Today I think we feel disappointed because we dominated the 90 minutes but were not aggressive in the last third in the way you expect.
It will still be a night to remember for Colchester despite failing to manage any shot on target in 90 minutes.
Goalkeeper Dean Gerken, who saved Eriksen’s spot-kick, and Lapslie were the heroes.
Boss John McGreal said: “It’s a great night under the lights, absolutely fantastic.
“It’s a fantastic night for the players and the club and even the staff.
“When you are coming up against the players of Tottenham’s calibre, sometimes on these type of nights you need a bit of luck.
“We have had a run around, we have got some tired legs in there. It’s a great occasion for us.”
