Lazio president Claudio Lotito admits he may buy in January.

Lazio are among the title contenders going into the winter break.

"We are certainly pretty satisfied, but the best is yet to come," smiled the patron after their 1-0 victory away to Sampdoria.

"This squad has the potential to challenge everyone and just needs to grow in terms of mentality. We played like a great team on Saturday, while in other occasions we did not.

"If after the Christmas break the side continues to play like it did here, then without underestimating any opponent I say we could do very well.

"If there is the opportunity to make some investments in January, then I will not be unprepared, but first we must cut down the squad. There are players here who haven't got much space."
