The Chicago Fire signed Brazilian midfielder Alex Monteiro De Lima on a free transfer from Swiss side FC Wohlen on Thursday and he will join the club when the transfer window opens June 27.

The 23-year-old De Lima began his career with FC Gossau in the 2009-10 Swiss Challenge League and, after one season, transferred to Wohlen and had seven goals in 44 matches over the past two seasons.

"Alex is a special player that we're proud to add to our roster," Chicago boss Frank Klopas said. "After having the opportunity to see him play for Wohlen last year, Alex joined us for part of our preseason where he showed the ability to contribute to our club."

De Lima appeared as a trialist in two matches for the Fire earlier this year.

"I'm looking forward to joining the Chicago Fire during the summer transfer window," De Lima said. "I hope that my skill and experience will assist as the Fire push for a MLS Cup Playoff spot."

He will be added to the Fire roster this summer, pending receipt of his P1 Visa and International Transfer Certificate (ITC). Per Major League Soccer and club policy, terms of the deal were not disclosed.
