It is never a negative to sign a good player, but the arrival of Lucas does raise questions as to where he is going to fit in at the club.
"It's sad", he told Canal+ when a move became inevitable in mid-January. It's no good for defenders to provoke me because I'm going to provoke even more.
That no room whatsoever was found for Lucas is surprising.
When PSG splashed £38m to take the Brazilian from Sao Paolo five years ago, he was considered one of the next young South Americans ready to take Europe by storm. Here he could have been used a lot more but I'm not the owner of the team, not the owner of Paris. It is not a signing that if he doesn't score goals from the beginning, it is a mistake. In the 2016-17 campaign he scored 12 goals in Ligue 1 and provided five assists. Only Edinson Cavani got more.
As Lucas was paraded at Wembley at half-time as his new side defeated the one that he might have joined 2-0, he would have been aware of the fresh challenge that now faces him. Six or seven months with no play, it is hard. We knew that if you bring in a player on the last day we knew that we didn't have the space then for some players.
"It will be massive for us to win", Pochettino said.
