I have to try to improve my players in the offensive phase.
Sarri, who dismissed the prospect of recalling strikers Michy Batshuayi and Tammy Abraham from loan spells at Valencia and Aston Villa respectively, watched his side fail to score for the second successive home league game.
"We have Morata, and Hazard can play very well in this position as we have seen in the last two, three matches, so I think that in the moment I don't need another striker". I have to think of the training.
The tepid and one-paced performance raised more questions about the need for a top-class striker on a day they splashed out £58 million (S$99.7 million) on Borussia Dortmund midfielder Christian Pulisic.
He, therefore, stated that his side must try to solve the problem of lack of goals before the winter transfer window is over if they must progress as well.
For the moment, Sarri continues to use Willian, but the Brazilian's bid to prove his worth was ruined when he was forced off with an injury late in the first half.
Hazard looked more vibrant back in his favoured winger role, but failed to torment the Saints once again despite having been involved in seven goals against them in the last six matches in all competitions. Sarri told the press after last nights game.
Substitutes Cesc Fabregas and Ruben Loftus-Cheek then combined to tee up Morata but Gunn blocked his low shot.
Despite dominating against Leicester, Sarri's team were beaten 1-0 as they paid the price for lacking the incisive passing and movement needed to break down the visitors' obdurate defence.
