Owen Coyle has confirmed he is eager to strengthen his midfield before the start of the season, as reports suggest Bolton are closing in on a deal for Carlos Sanchez.
The Trotters have been linked with a move for the tough-tackling Colombian for much of the summer after being impressed with his performances for Valenciennes over the past few seasons.
A number of other clubs are thought to be monitoring his situation and it is reported that Bolton have now made a take-it-or-leave-it offer to the 26-year-old after meeting him over the weekend.
Coyle admits he is in need of a midfield enforcer after a disappointing display in Saturday's 3-0 friendly defeat against Portsmouth, and he will try to bring in somebody over the next few days.
"There might be some merit in that," he told Bolton News. "We lost two goals on the counter-attack which we might not have lost had we had a more defensive type.
"We've always been in the market for that type of player and if the right one becomes available then we will certainly have a look at it.
"Can we get one by the start of the season? Well, we'll certainly be trying to."
Meanwhile, Coyle has revealed that David Ngog was taken off against Portsmouth as a precautionary measure, with the striker expected to make a swift recovery from a back problem.
"David has thrown his back again, which is not ideal," he said.
"He looked terrific the other night at Morecambe but we only wanted to give him another 45 minutes. When he felt his back again, we couldn't take any chances."
